daSDC seems like a crazy site for angry fury people who likes to take their aggressions out on the piano. and yes they would probably know. i could ask these crazy people.
You know, this is the wrong forum to ask these questions. Check out daSDC (https://dasdc.net). It's devoted to things like these.
la campanella must be very popular at da SDC. i can imagine other piano pieces that is their favorites. godowsky etudes, islamey, rachmaninovetudes etc.
i played liszt la campanella. and it had much jumping that reached all the way up to 2 octaves. is there any other songs that has more inzane jumping than that??
