Which console has the most diversity in quality titles?

[Bodhesatva]

The PC.

If this is a usual "PC doesn't count!" thread, then either the DS or the 360, but both benefit from having been out the longest. Or do they not count because they've had considerably more time on the market? I always get confused what the rules are in these types of threads. Usually it just depends on the who the original poster is, and what point he's trying to make.
