I recently discovered Bill Burr and liked his act. Netflix has a few specials up that are very good to watch when vaked:
Chris Porter - Ugly and Angry
Steve Bryne - Champion
Tom Papa - Freaked Out had me
Jim Bruer - and Laughter for All
Demetri Martin - All the Time reminds me a bit of Mitch Hedberg
These sucked:
Colin Quinn - Unconstitutional
Tom Segura
John Mulaney
anything Doug Benson I know some potheads love him but he's retarded
