For me: All of the above, in addition to the following:
: Man, this guys utterly forgotten due to the "Real" Ghostbusters (which incidently was also a good show!). But this show was a good show in it's own right, not a poor-man's clone like the Go-Bots were to Transformers.
Superted: It's Superted! 'Nuff said.
: Absolutely legendary show.
X-Men: One of the best from teh 90s.
(90s) Spiderman: NOT the god-awful 60s one which only had about 7 different animation slides in total.
: Captured the detective comics Batman feel perfectly.

Incidently, the current TMNT and Batman cartoons they have out aren't actually that bad. Unfortunately the same can't be said of X-Kids.

Now let's take this moment to appreciate ALL 4 different intros from Transformers!
Season 1: That one horribly off-key guitar note brings a tear to my eye every time I hear it. Ah, the memories...
Season 2: Probably the best!
Season 3: Techno transformers!
"Season 4" (if you can call it that): Essentially just a 2-episode rehash of sesaon 3 intro introducing about a million new transformers (insert headmasters) in an attempt to sell more toys. (BTW, the die cast toys of the 80s were excellent, but by this time they were using cheapy plastic).
