I think you may be a little biased since your older now. Your list is pretty spot on but I enjoy chowder and Regular Show, mainly because i dont really have to think, its just mindless and i find it hilarious the stupidity and randomness of the Ideas. Both shows are very original too.

I'll agree with you on most of these, but I'm gonna have to disagree on Gumball and Regular Show.
Gumball - I like seeing the way different animation styles can come together, and it helps give each character their own distinct personality.
Regular Show - It can be as surreal as Adventure Time, but is much more subtle, surprisingly crude, and a good throw-back to the 80s without referencing anything from the 80s.
One show that should've made the Bad list for sure is MAD. It's a poorly done attempt at parodies for children, but a lot of the jokes are lost because they parody movies that kids may not have seen (see also a Toy Story and Bourne Identity hybrid).
Johnny Test is a show that I don't know where it belongs on your list...it's a hit and miss show. While at times it has some interesting ideas, poor lip syncing, annoying sound effects, and enough cliches make it a little difficult to watch at times.
Just my thoughts on the subject. Vivan las Cartoons!

As for my thoughts on Johnny Test (the one that I forgot to mention), I just think its a recycled and rehashed version of Dexter's Lab with a role reversal and quite possibly the dumbest name for an antagonist: Bling Bling Boy.
