Adventure Time and Bob's Burgers are probably the most important one for its impact. The way its written, a very casual, extremely loose way of speaking, is now basically dominant.
Bojack was really great for when it was good, kind of fell apart a bit.
Over the Garden Wall is really great, and it being a limited series that was made to be so is a huge advantage in that it tells a coherent story with a beginning/middle/end.
Those are my favorites there.
