Around here everyone seems to like Sirius programming better. If you like rock Octane 20 is the ish. I have had both and honestly after having sirius I wouldnt pay for XM, I would rather have just FM and CDs if Sirius wasnt a option.
I also think Sirius spend more money on programming than XM. Xm dumps alot of what they could be spending on good programing with their marketing tactics. That is why some people praise Xm,they have had it crammed down their throats. Xm sends us god knows how much marketing material each month to the shop. We dont sell much XM because we prefer Sirius, and XM still sends us 50lbs of literature, banners, and lifesize celeb standups each month that we just throw away. Sirius doesnt spend that kind of money, and I think it reflects in thiere programing.
