Really hard to say. It's one of those times when you know you've watched a ton of cartoons, but none come to mind when asked. I'll give it a try:

1. My Little Pony: Friendship is Magic - Best animated show in my book. Shared so many memories and fun with this show.
2. Beast Wars: Transformers - Show that introduced me to Transformers and shaped my Transformers fandom ever since.
3. Justice League/Unlimited - Show that introduced me to the appeal of superheroes and solidified them, especially with Batman. Showed me how superheroes were like modern myths.
4. Star Wars: The Clone Wars - Takes the movies' potential and expands it with jaw-dropping space and land battles, awesome saber duels, and genuinely interesting characters.
5. Avatar: The Last Airbender - Made me believe that a Western cartoon could tell an epic, self-contained fantasy full of beauty and richness.
6. Teen Titans - Wacky, zany, fun, yet serious when it needed to be, showed me not to judge a show by its cover.
7. Transformers Animated - See what I said about Teen Titans. Remains the single best reinterpretation of the Transformers mythos and has the most fully living, breathing world of all the series.
8. Dexter's Laboratory - Had tons of fun with this as a kid.
9. Tom and Jerry - Same as Dexter, spent hours rewatching these.
10. DuckTales - Who knew the adventures of an old money-faced duck and his three kid nephews could be so epic?

Honorable mentions: The rest of the DCAU, Kim Possible, Reboot, Looney Tunes, Darkwing Duck, Chip n' Dale Rescue Rangers, Avengers: Earth's Mightiest Heroes, Avatar: The Legend of Korra, Totally Spies, The Powerpuff Girls, all Hanna-Barbera cartoons and Men in Black: The Animated Series.

Phew, that was a tough one.
