I only have XM in my car, but the sytem in the car is decent as far as mobile goes (all ADS drivers except the JL subs, and MacIntosh providing the watts for the mids/highs).Needless to say I've only listened to the analog output of the XM receiver, and I'm also using the XM FM modulator (wired) to get the signal to my head unit.
I have to admit, all things considered, it's not bad. CDs do sound far better in my car, but XM definitely sounds better than FM (I might choose FM over XM quality if the car were sitting still, but in motion it's an easy call).
One thing to realize is the quality of the rips vary greatly with XM, and also the rips can do weird things to songs. It's obvious that different songs were compressed differently than others. The weird effect is when the compressed songs sound as if they'd been mixed differently. For instance, a rhythm guitar may be brought forward in the mix in a way that analog compressors would never do it. I don't spend any time listening to MP3s, though so this effect may be common with lossy compression for all I know (I realize lossy digital compression is something entirely different from analog compression).
The reason you keep hearing about the content and not the quality is that the content is so good the quality is less relevent, especially for car use. Also, the quality is nothing to write home about - neither great nor awful - so it simply doesn't generate much interest.
If I had XM at home, I doubt I'd do any serious listening to it (I'd just go buy the CDs of stuff I like), but I would use it ALL THE TIME for background music. I don't like being a DJ.
