Favorite characters?

Adrian, George, Ashely (s1-s2), Donavan and Betty

Adrian and Ricky.

Original Adrian and Ricky, though, back when they were complex and interesting characters (and before Ricky became a Gary-Stu for the sake of Ramy).

{Look at me and mah clevah nicksies.}

George was funny. I did like Reuben, Adrian, Ricky, Ricky and Adrian together, Ricky and Amy together (not Amy with anyone else), Ben and Adrian together (I didn't think Ben and Amy worked well together especially since Ben was a stalker when it came to Amy). I liked Henry and Alice and Lauren and Lauren's dad. I liked Ricky's foster mom and eventually his physical mom. Tom was okay even though they sometimes had him being a bit rude at times.

George

I'm only on S3, but I'd have to say, so far my list would be:
Ricky
Betty
Bunny

When the man whore and ex-hooker top the list, it's clear the show could have done better.
