Either one is better than my 3000, but both are only as good as the player at the keys.
+1 on that! The key is to pick an arranger that meets your preferences (size, weight, "personally" important features, sounds, and styles) and then focus your efforts to capitalize on that keyboard's strengths. Today's arrangers are all high quality - and all are capable of generating amazing results.
