I know what you mean, I feel this is why Liszt is sometiems hated and why I personaly prefer Chopin. Liszt often put unnecessary virtuosic stuff into his pieces, well, because he could play them, but they not add anything to the music, usually some crhomatic hard to play stuff which really do not have to be there. Liszt was a great pianist but also a bit of a narcissistic personality when it cames to piano skills, so he really wanted to show that virtuosic stuff.
