I found the Yamaha more difficult to program and use during dynamic performances. I have an original Fantom and a Fantom X and love them. I program all my own sounds, so factory presets are not much of a factor. With the 88's I think the best thing would be to play the weighted keyboards and see which one feels better. You really cannot go wrong with either machine, though - so maybe even consider which on you can get the best deal on.
