Actually, I don't think you can conclude very much from such comparisons. In fact, Roland wins this one sky-high IMO, which I didn't expect at all. But it's not because Rolands sounds are better in general, but just because of the individual choice the two users made among the range of sounds available. It could sound very different with the same instruments if other selections had been made. Probably not a real help as a purchase decision, I'm afraid.
