If I may reply:
On Korngold, I wouldn't look foward to his later works. His output, like that of that (arguably) of many child prodigy composers, declined with age. Also, if that sonata pleased you, I suggest looking into some of his miniatures. When the structural pressure was off, his work is particularly delightful.
On Mozart vs. Clementi, I beg you to take a closer look.
Clementi's sonatas are simply more adventurous and thoughtful. While Mozart's are always accompanied by the usual inhuman perfection and superb melodic invention; after a time that constant Alberti bass is like
a mallot hitting my brain. (In tempo, of course.)
Clementi underappreciated? Obviously. Better? I'm afraid so.
P.S. Despite the words of war, I am indeed appreciative of
your generosity with the Horowitz transcription.
