Hated AD at first, but now I prefer it to FG. FG still has it's moments, but AD has been the more interesting one as of late.

CS always sucked.

American Dad the quality of the show keeps progressing.. since Seth has been mainly working on FG he hasn't touched AD. WHICH is good
The Cleveland Show had way too many racial/gay jokes(I can handle them but they were just boring).. It was repetitive.
Family Guy is legendary but has gone down in quality lately.

American Dad. It's easily the wittiest and best written. It's because all of FG's good writers left after season 3 and went to work on AD, and it clearly shows. AD doesn't have to rely on gags and long-winded cutaways.

All three are beyond terrible.

TCS is awful.

And AD.

American Dad gives me life every time I watch it
