I have XM but from what I can tell they're virtually identical music-wise. They differentiate mainly in terms of things I suspect neither of us cares about: baseball vs football, the two big shock jocks, and station ID jingles. In other words, they're within two degrees of identical.
Sirius is said to have slightly better audio quality, or was a year or two ago. I doubt that a little bit; they both tweak & tune the bandwidth allocations constantly, so it varies from channel to channel and is based upon the number of channels crammed into the available pipe at a given time, and the encoding quality assigned to each of them based on whatever opaque metrics they use to make those decisions.
