Had to get that in.... When I got my XM I researched the two companies and after reading where if one lived in the bigger cities like NYC, LA, Chicago etc that had lots of skyscrapers etc then Sirius was better reception than XM for whatever reason and out in the boonies XM was better...why I dunno but that and the programming listed at the time was better and I chose XM.
Sat Radio has been one of my better "gadgets" added to my vehicle. Awesome form of media for road trips and emergencies where local stations may be down (hurricane etc )!
Opie & Anthony XM radio !!.......:o)
Funny, my Siriius seems to be just a bit better than my husbands XM, when in the mountains. . .could be just a biased observation on my part. . . ;^) and my car is bigger. . .a little 'higher'. . .
