When it comes to voices, Yamaha definitely is head and shoulders above the pack. Styles, well how many third party styles do you find out there for the other machines--again, Yamaha gets the nod. Yammies will keep the folks on the dance floor, and that my friends is all I want to do with any keyboard.
Cheers,
Gary
