I remember my buddy getting a brand new PS2 just after I got my DreamCast... (Oops...) And I always thought it had some solid releases (graphics and controllers were fine, too).
However, the 64 was the most ground-breaking console in my eyes. (And yes, the controller is trash)
The PS2 library is just too much. It always seemed like they were just throwing shit out there, trying to see what would stick, whereas Nintendo seemed to know what had staying power.
One thing I'll give you is the RPGs
