Between those two top 10s, I'd easily take the 90s, with Kablam being the only show I didn't enjoy on that list, while I only liked Avatar, Foster, and ZIM from the 2000s.
The 2000s still had great cartoons though; Courage and Ed, Edd, & Eddy both in their prime, Time Squad, and several Adult Swim Shows (depending on whether or not you'd place them in the same category, since AS cartoons aren't necessarily child-friendly).
