I think Liszt's reputation still suffers from the "knee jerk" reaction that has lingered from the 19th century where many music critics/followers couldn't separate the musician from the showman. Chopin was initially bowled over by Liszt's playing, but later criticised his composing skills; however, Chopin died before Franz got into his stride as a composer. Liszt's music skill were mind blowing. In his day he was recognised as the greatest sight reader, the great improvisor and of possessing the greatest music memory.
