XM or Sirius

I agree also with Mike above, sat is the way to go in cars if you don't mind non-audiophile sound. And for rg, tell your son to use the home antennae on his dash and use the mobile antennae at home, works MUCH better.
MMM

I have had both services and IMO Sirius is better because I mostly listen in a car or party situation, and Sirius plays more popular tracks.....for being in a car or at a party that is more pleasing, I also like Sirius more because of the DJ and music news, to me XM is more like Musac......sorta lifeless and they do dig alot deeper into music as far as unknown tracks, so if you like more variaty XM will work for you, but Sirius is more entertaining and plays more popular songs, as far as Audiophile quality it isnt gonna happen.....I much prefer the Music Choice channels on my TW cable for at home sound quality. So in short I think you should choose based on programming not quality, and I hope some info I gave helps.

either is like discovering music on the radio for the first time....no its not audiophile, but who cares...the comeday stations too are worth the price.

Jaybo, I completely agree. My wife gave me an XM receiver for Christmas and I had flashbacks to the best radio shows and formats I've listened to over the past 30 years. I'm more than a little bummed that they took the Prog/Jamband channel off the air but I can still get a fix online.

As stated above, XM playlist is deeper. To me, that means listening to pure crap half the time. I have had both and much prefer Sirius. Those who complain about the sound quality are probably using the FM modulator. (antenna) Use the adapter and go straight to the head unit if you have aux. input. VERY close to CD. BEWARE of the lifetime deal....it is for the lifetime of the reciever! When your radio dies your subscription dies with it.
