I have had both and prefer xm over Sirius overall. I like Sirius programing slightly over xm, but there playlists seem to repeat far more than xm. Sirius also had a lot more signal drop outs and fade aways where the xm signal was strong.
In the same car with the same system and same antenna location, the xm sounds better than Sirius.
Xm Comedy 150 is bad ass. But as far as the rest of the programming don't really care.
Sirius has the same thing..They have 2 comedy channels.1 is censored one is not...
It's the soldier not the reporter who gives you the freedom of the press It's the soldier not the poet who gives you the freedom of speech It's the soldier not the campus organizer who allows you to demonstrate It's the soldier who salutes the flag, serves the flag, whose coffin is draped with the flag that allows protesters to burn it
Another vote for Sirius. Had XM in the truck and Sirius through Dish Network. Cancelled XM because the programming had no variety. The Sirius through Dish rocks...now wanting to get that for the road. That playback unit looks awesome.
