need help picking up satelite radio

what is better XM radio or sirius radio and who haves the most techno euro dance and all of that on XM or sirius and which one u pay 4 less and which one more thnx

I think they pretty much use the same sats

My boss has XM radio at the restaurant i work at and there is only one station for euro/techno on XM i believe but i have only heard it once (everyone else at my work hates techno, i don't understand why). XM is the cheaper one by about 10-20 bucks last time i checked. haven't really listened to sirius but i hear it has less commercials and is a little better on not repeating songs (not by much) and offers less music stations, but has all the good sports ones (NFL, NBA, others). i would go with sirius just for howard stern.
