Silver Age for me. With shows like SpongeBob at its finest, FOP at its best, Invader Zim, My Life as a Teenage Robot, ChalkZone, Drake and Josh, and Danny Phantom, what's not to love about this era? Sure, it had a few duds like All Grown Up, but I say that most shows were just fantastic. Golden Age also had good shows like All That, Rocko, Ren and Stimpy, Rugrats, Kenan and Kel, and Hey Arnold, but I don't really remember the 90s because I was born in 1998 :p. Bronze Age also had gems like Kappa Mikey, Back at the Barnyard, Making Fiends, iCarly, and The Mighty B (yeah, I liked it).
