I really like the cartoon shorts from the 30's, 40's, and 50's and a few TV toons.
Particular Favorites of mine are:
Disney's Silly Symphonies
Tom and Jerry (unedited)
Bugs Bunny (unedited)
The Raccoons
Silverwings
Gargoyles (First few seasons)
Chip 'n' Dale's Rescue Rangers
Scooby-Doo! Where Are You?
Droopy (unedited)
Roadrunner and Wile E. Coyote
The Animaniacs
I liked these, because they just stood out as good animated shows with great writing and great characters with some good business like great action and funny gags.
By the way, Silver Wings is something I highly recommend. It was based on a book by Kenneth Oppel and skillfully animated by the Canadian production house, Bardel Animation. It's about bats. The character designs of the bats, I think are incredible combination of human and animal attributes. It's a shame it's no longer on TV, but I think the first and only season is on DVD.
