XM vs Sirius?
 

Obviously Sirius has Howard going there but I am in it more for the music (All though I can't really stand Opie & Anthony and would much rather Howard in a year). Anyway I am a UPOP addict and don't know if I could live without it now, unless Sirius has a similar station. I was browsing their site and nothing popped out at me. Anybody here have a preference?

Sirius has a free trial where you can listen to all of the stations online. Check out their site.

Sirius gets superior reception because of how their satellites are orbited and you can point the antenna straight instead of how you have to have a southern position with XM.
