Play both, extensively.. Decide for yourself. It is of course the owners of these respective boards that are recommending THEIR particular choice, without asking a bit more about your musical tastes and direction...

How much price difference between the two? How important is key feel? Are you EVER likely to want to use a sampler? Do you primarily play arranger style, or use SMFs or mp3's?

Questions like this should be asked and answered before an answer is anything more than partisanship, IMO... Ask a man with an apple in his hands whether he prefers apples or oranges. Guess which answer you'll get...?
