I love my XM but honestly I'd rather have Sirius due to NFL games. I don't know how the rest of the channel lineup looks but that's a biggie for me since I'm a huge football fan. I got XM when I got a free receiver and a 15 months for $77. When that's up I may give Sirius a try, especially since I can integrate it into my BMW's stock radio (if I grab a newer one on eBay anyway).
