They all do the job well but differently...I have used most of them and was successful on each no problem.......what you need to ask yourself is am I comfortable playing this keyboard....navigationally, editing, onboard features, etc, ... with only a few brands left they pretty much sound terriffic with styles and sounds ........and no matter what you choose ...a few years later it will become antique thats the way electronics work...eg: iPhone 2,3,4,5,6,7,8 etc.. so I say just buy and play it wont be your last....good luck
