+1 to above. yes there is ample reason when it comes to Bach, Mozart, Beethoven to dump on Schirmer, but their edtitions of modern works are good.

w regard to OP, you'll need to check contents but the "Great Performers Edition" by Earl Wild for Liszt pieces, there were 2 volumes at least that I know of had really fantastic notes/insights into the pieces by one of the performance giants of the 20th century. I recall seeing some publisher samples for a few pieces int he past and there were some smart fingering suggestions. Generally anything Earl Wild touched is gold.

For Liszt you might also seek out I think in Peters edition by Sauer who was a pupil of Liszt, I believe those editions are a smart place to kick over rocks too.

Re Schirmer above, I'll nod to Joseffy and Mikuli for Chopin, they are not always considered "authoritative' but they are tasteful and their lineage ties to Fed himself makes them important reference tools even if one sticks to PWM and similar.

for more elementary suggestions see if the Alfred student or masterworks edition is available, usually w notes by Hinson or Baylor. Those are pretty good, never had much to complain about from them.
