Lee Evans is alright, but despite stand up being his job, I always get the feeling he's really uncomfortable on stage. He does some amazing jokes and great routines, but he just always seems really nervous and it usually takes him a while to get into it and become more relaxed.
That said, he has grown in years, his later stuff has been amazing.
Ricky Gervais is funny, yes, and I do enjoy watching his stand up, but really, if you listen to his radio show you get the same thing and neither are on par with any of the great stand up performers.
Peter kay can be funny when he's not stealing other peoples jokes or falling back on tired old routines (Garlic Bread has gotten a little old now).
