I'd like to get one and I hear Sirius is better for sports. Mostly interested in the NFL and college.
Talk shows would be nice but neither seems to carry the syndicated shows.
I can't speak for Sirius, but XM has Tony Snow, Hannity, Laura Ingraham, Bill Bennett, Michael Medved, etc. -- and even Air America! They have a channel "America Right" and another "America Left". Rush is not on Sirius or XM -- and probably will never be.
