You can break it down into as many catregories as you like.
For me, I listen to a lot of ESPN radio as my job requires a lot of road time. So for like I'll go
Mike and Mike. Easy to listen to and informative.
For least liked on a national perspective. Dan Patrick. Guy's so in love with himself it's pathetic. Jim Rome a close second.
For tv.
Love: PTI. Wilbon and Kornheiser got good chemistry
Hate: Rome is Burning. Anything with Jim Rome in it is going to suck.
