Rachmaninoff - Mozart.
1. Piano Concerto No. 3/Le Nozze di Figaro.
2. Vespers/Piano Concerto No. 20.
3. Piano Concerto No. 2/Symphony No. 41.
4. Symphony No. 2/Requiem.
5. Symphonic Dances/Don Giovanni.
6. The Bells/Symphony No. 40.
7. Etudes Tableaux Op. 39/String Quintet No. 4.
8. The Isle of the Dead/Clarinet Concerto in A.
9. Preludes Op. 23/Piano Concerto No. 23.
10. Trio Élégiaque #2/Great Mass in C minor.
And if we're looking completely at quality over quantity (which I think is a flawed way to look at it considering some composers wrote large quantities of good - great music), as well as neglected the level of innovation/originality (another important aspect in evaluating composers) here are some other top 10's (of the ones I put in front of him) (I like lists and currently have a lot of time on my hands).
Bach.
1. Piano Concerto No. 3/Mass in B minor.
2. Vespers/The Well-Tempered Clavier.
3. Piano Concerto No. 2/St. Matthew Passion.
4. Symphony No. 2/Die Kunst der Fuge.
5. Symphonic Dances/Goldberg Variations.
6. The Bells/Concerto for 2 Violins in D minor.
7. Etudes Tableaux Op. 39/Cantata #82 “Ich habe genug.”
8. The Isle of the Dead/St. John Passion.
9. Preludes Op. 23/Passacaglia and Fugue in C minor.
10. Trio Élégiaque #2/A Musical Offering.
I think Bach wins here quite easily. Bach was also far more varied, prolific, and had a higher quality percentage (if we kept going Bach would eventually overwhelm), as well as being a far more important composer.
Beethoven.
1. Piano Concerto No. 3/Symphony No. 9.
2. Vespers/String Quartet No. 14.
3. Piano Concerto No. 2/Missa Solemnis.
4. Symphony No. 2/Symphony No. 5.
5. Symphonic Dances/Symphony No. 3.
6. The Bells/Piano Sonata #29, “Hammerklavier."
7. Etudes Tableaux Op. 39/Piano Sonata #32.
8. The Isle of the Dead/Beethoven: Piano Sonata #30.
9. Preludes Op. 23/Diabelli Variations.
10. Trio Élégiaque #2/Piano Sonata #23 "Appassionata."
Again, Beethoven, I think, wins. Beethoven also had a much higher percentage of good music, and he was one of the most revolutionary and original composers in the history of music.
Schubert.
1. Piano Concerto No. 3/Winterreise.
2. Vespers/String Quintet in C.
3. Piano Concerto No. 2/Piano Sonata #21.
4. Symphony No. 2/Symphony #9, “Great."
5. Symphonic Dances/String Quartet #14, “Death & the Maiden."
6. The Bells/Symphony #8, “Unfinished."
7. Etudes Tableaux Op. 39/Impromptus, D.899.
8. The Isle of the Dead/Piano Quintet "The Trout."
9. Preludes Op. 23/Die Schöne Müllerin.
10. Trio Élégiaque #2/Piano Sonata #20.
I think this top 10 is getting closer in terms of quality (although i'd still give it to Schubert), and Schubert, again, was a much more important composer.
Brahms.
1. Piano Concerto No. 3/Symphony #4.
2. Vespers/Clarinet Quintet in B minor.
3. Piano Concerto No. 2/Piano Concerto #2.
4. Symphony No. 2/Ein deutsches Requiem.
5. Symphonic Dances/Piano Quintet Op. 34.
6. The Bells/Symphony #1.
7. Etudes Tableaux Op. 39/Violin Concerto Op. 77.
8. The Isle of the Dead/Piano Concerto #1.
9. Preludes Op. 23/Symphony #3.
10. Trio Élégiaque #2/Piano Trio #1.
Again, Brahms wins (IMO) by quite a bit, and wrote more great music.
Wagner.
1. Piano Concerto No. 3/Der Ring des Nibelungen.
2. Vespers/Parsifal.
3. Piano Concerto No. 2/Tristan und Isolde.
4. Symphony No. 2/Die Meistersinger von Nurnberg.
5. Symphonic Dances/Siegfried Idyll.
6. The Bells/Lohengrin.
7. Etudes Tableaux Op. 39/Tannhauser.
8. The Isle of the Dead/Der fliegende Holländer.
9. Preludes Op. 23/Rienzi.
10. Trio Élégiaque #2/Wesendonck Lieder.
Wagner wins quite handily. He, like Beethoven, was also one of the most revolutionary composers. Rachmaninoff was more versatile.
Haydn.
1. Piano Concerto No. 3/Symphony #104, “London.”
2. Vespers/String Quartets op. 76.
3. Piano Concerto No. 2/The Creation.
4. Symphony No. 2/Trumpet Concerto in E-flat.
5. Symphonic Dances/Mass #11, "“Lord Nelson Mass."
6. The Bells/The Seven Last Words of Christ.
7. Etudes Tableaux Op. 39/Cello Concerto #1.
8. The Isle of the Dead/Symphony #101, "Clock."
9. Preludes Op. 23/Piano Sonata #62.
10. Trio Élégiaque #2/String Quartets op. 64.
Getting closer, but I still think Haydn wins. He was also wrote more good works and was a far more important composer.
Mahler.
1. Piano Concerto No. 3/Das Lied von der Erde.
2. Vespers/Symphony #2, “Resurrection”
3. Piano Concerto No. 2/Symphony #9.
4. Symphony No. 2/Kindertotenlieder.
5. Symphonic Dances/Symphony #4.
6. The Bells/Symphony #6, "Tragic."
7. Etudes Tableaux Op. 39/Rueckert Lieder.
8. The Isle of the Dead/Symphony #1, "Titan."
9. Preludes Op. 23/Symphony #5.
10. Trio Élégiaque #2/Symphony #3.
Mahler wins by quite a bit, Rachmaninoff was more versatile and wrote more high quality music. Mahler wrote a higher percentage of good works.
Handel.
1. Piano Concerto No. 3/Messiah.
2. Vespers/Giulio Cesare.
3. Piano Concerto No. 2/Water Music.
4. Symphony No. 2/Concerti Grossi, op. 6.
5. Symphonic Dances/Music for the Royal Fireworks.
6. The Bells/Coronation Anthems.
7. Etudes Tableaux Op. 39/Dixit Dominus.
8. The Isle of the Dead/Solomon.
9. Preludes Op. 23/Israel in Egypt.
10. Trio Élégiaque #2/Ariodante.
Handel just edges him out, I say. Again, he also was more prolific in writing good music and was more important.
Stravinsky.
1. Piano Concerto No. 3/The Rite of Spring.
2. Vespers/The Firebird.
3. Piano Concerto No. 2/Petrushka.
4. Symphony No. 2/Symphony of Psalms.
5. Symphonic Dances/Concerto, "Dumbarton Oaks."
6. The Bells/Mass.
7. Etudes Tableaux Op. 39/Pulcinella.
8. The Isle of the Dead/Symphony in Three Movements.
9. Preludes Op. 23/Agon.
10. Trio Élégiaque #2/L'histoire du soldat.
Could go either way, but Stravinsky was, again, far more important and innovative.
Tchaikovsky.
1. Piano Concerto No. 3/Symphony #6, "Pathetique."
2. Vespers/Violin concerto, Op. 35.
3. Piano Concerto No. 2/Piano Concerto #1.
4. Symphony No. 2/Symphony #4.
5. Symphonic Dances/Symphony #5.
6. The Bells/Swan Lake.
7. Etudes Tableaux Op. 39/Romeo and Juliet Fantasy-Overture.
8. The Isle of the Dead/The Nutcracker.
9. Preludes Op. 23/Piano Trio, Op. 50.
10. Trio Élégiaque #2/Manfred Symphony.
I think Tchaikovsky wins here, and it also has to be said that Rachmaninoff wouldn't have been what he was if not for Tchaikovskies influence.
Verdi.
1. Piano Concerto No. 3/Otello.
2. Vespers/La Traviata.
3. Piano Concerto No. 2/Requiem.
4. Symphony No. 2/Rigoletto.
5. Symphonic Dances/Aïda.
6. The Bells/Il trovatore.
7. Etudes Tableaux Op. 39/Falstaff.
8. The Isle of the Dead/Don Carlos.
9. Preludes Op. 23/Simon Boccanegra.
10. Trio Élégiaque #2/La Forza del Destino.
Verdi by a fair margin, but Rachmaninoff was a more varied composer.
Schumann.
1. Piano Concerto No. 3/Piano Concerto.
2. Vespers/Fantasie, Op. 17.
3. Piano Concerto No. 2/Dichterliebe.
4. Symphony No. 2/Piano Quintet, Op. 44.
5. Symphonic Dances/Davidsbündlertänze.
6. The Bells/Symphony #4.
7. Etudes Tableaux Op. 39/Kreisleriana.
8. The Isle of the Dead/Carnaval.
9. Preludes Op. 23/Symphony #2.
10. Trio Élégiaque #2/Symphonic Etudes.
A tie, but Schumann wrote more music of a high quality and was a more important composer.
Liszt.
1. Piano Concerto No. 3/Piano Sonata.
2. Vespers/Christus.
3. Piano Concerto No. 2/A Faust Symphony.
4. Symphony No. 2/Années de pèlerinage. Deuxième année; Italie.
5. Symphonic Dances/Missa solennis zur Einweihung der Basilika in Gran.
6. The Bells/Douze études d'exécution transcendante.
7. Etudes Tableaux Op. 39/Eine Symphonie zu Dante's Divina Commedia.
8. The Isle of the Dead/Années de pèlerinage. Première année; Suisse.
9. Preludes Op. 23/Harmonies Poétiques et Religieuses.
10. Trio Élégiaque #2/Fantasy and Fugue on the chorale Ad nos, ad salutarem undam.
A tie, but Liszt wrote more music of a high quality, was more versatile, and was also one of the most revolutionary composers (he was also a huge influence on Rachmaninoff, perhaps more than any excluding, perhaps, Tchaikovsky). Rachmaninoff has a higher percentage of good - great works, but there are many reasons for that as far as Liszt goes, mainly that often he wasn't writing for a purely aesthetic purpose.
Berlioz.
1. Piano Concerto No. 3/Les Troyens.
2. Vespers/Requiem Grande Messe des Morts.
3. Piano Concerto No. 2/Romeo et Juliette.
4. Symphony No. 2/Symphonie Fantastique.

8. The Isle of the Dead/L'Enfance du Christ.
9. Preludes Op. 23/Te Deum.
10. Trio Élégiaque #2/Roman Carnival Overture.
I think Berlioz wins here. Rachmaninoff was a more varied composer and wrote more high quality music. Berlioz was a far more important composer, perhaps the most original composer who ever lived.
Richard Strauss.
1. Piano Concerto No. 3/Vier letzte Lieder.
2. Vespers/Eine Alpensinfonie.
3. Piano Concerto No. 2/Der Rosenkavalier.
4. Symphony No. 2/Tod und Verklärung.
5. Symphonic Dances/Ein Heldenleben.
6. The Bells/Salome.
7. Etudes Tableaux Op. 39/Metamorphosen.
8. The Isle of the Dead/Till Eulenspiegels lustige Streiche.
9. Preludes Op. 23/Also Sprach Zarathustra.
10. Trio Élégiaque #2/Elektra.
Tie, Strauss was more innovative.

6. The Bells/Piano Sonata No. 3.
7. Etudes Tableaux Op. 39/Piano Sonata No. 2.
8. The Isle of the Dead/Ballade No. 1.
9. Preludes Op. 23/Etudes Op. 10.
10. Trio Élégiaque #2/Fantaisie Op. 49.
Tie, if not a slight edge to Rach. Chopin was a far more original and important composer, wrote more high quality music and had a much greater percentage of good - great music. Rachmaninoff was far more versatile.

2. Vespers/Prélude à l'après-midi d'un faune.

2. Vespers/Concerto for Orchestra.
3. Piano Concerto No. 2/The Miraculous Mandarin.
4. Symphony No. 2/Music for Strings, Percussion, and Celesta.

8. The Isle of the Dead/Piano Trio #1.
9. Preludes Op. 23/A Midsummer Night's Dream.

Close.

8. The Isle of the Dead/Pavane pour une infante défunte.
9. Preludes Op. 23/Piano Trio.
10. Trio Élégiaque #2/Piano Concerto for the Left Hand.
Tie, although perhaps an edge to Ravel. Ravel far more innovative composer. Ravel higher percentage of good-great, Rachmaninoff more high quality works.

3. Piano Concerto No. 2/Symphony #7.

8. The Isle of the Dead/Symphony #4.
9. Preludes Op. 23/Mass No. 3.
10. Trio Élégiaque #2/Mass No. 2.
Bruckner wins here. Rachmaninoff far more varied and wrote more good - great music. Bruckner far more innovative.
Of course all of this is subjective (to an great extent), but I put in the effort to do all this because I think there are so many great composers that wrote so much great music, and I think that instead of worshipping Rachmaninoff seemingly at the expense of your appreciation of the other greats, maybe it would be prudent to put much effort into trying to appreciate these other composers and their music for what they are as well as Rachmaninoff. After all, many of these composers are generally considered to be greater by experts!
