Oh yeah, Jim Norton is definitely up there. I haven't seen much from Rich Vos but he's hilarious when I've heard him on old O&A clips on Youtube and more than one person has told me I need to see his stand-up. So I guess I'll have to check out his stand-up now.
I'm definitely a fan of Rogan's podcast, but I find his stand-up to be just okay. He's too inspired by Kinison. I can enjoy Kinison but it comes off as too much sometimes. But I did really like Rogan's last special, "Triggered." Probably his best stand up special since his early specials. Maybe even surpassing those early ones... maybe... Heck, I thought it was funnier than Burr's most recent special and I think Burr is the best stand-up comic currently in the business. Granted I thought Burr's latest was his worst special to date (not that it was bad, just didn't live up to my high expectations of him and maybe that's unfair, especially with how busy he has been the last couple of years with F is for Family--which I love, his podcast, etc).
