NSMBWii, while still fairly conservative and lacking in ambition or creativity, still felt polished and fun at the time, and 4-player mayhem was a nice addition to the formula. It was a decent game, just well below the standard set my previous 2D Mario entries.
NSMBU wasn't terrible per se, but by the time it came out (and as a launch title for a HD console) it just felt so lazy and tired.
Never played 2 or DS.
