The best bet would be try to go to a store, and go through all the channels on both XM and Sirius and see which one has more appealing stations if you are trying to pick from one of them. I'm actually more of a XM fan (due to it having better dance stations), but I actually only have Sirius (and only in my car, cuz it came with Sirius, but it needs to be fixed, as the antenna isn't working properly)..
So I like 62, 63, 64, 66, and 68 on Sirius. By the way, if you don't know, you can listen to any Sirius channel on any PC well if you have a Sirius subscription. Just go to
www.Sirius.com and login with the login and username you chose.
