My personal experience, subscribing to MusicChoice via DirecTV and XM:
Only 40 channels on MusicChoice, including several erzatz formats vs. 100 channels on XM, most of them music formats.
Sound quality: MusicChoice is dynamically compressed way more than it should be and non-skillfully. It's as dynamically lifeless as Muzak. It's really unlistenable on some music selections, to me. XM is more lively in dynamic range and sounds like the best mp3 file you ever heard but with better high-frequrency air/less high-frequency phasiness than any mp3, although you can hear some congestion in complex highs on some material. This all relates to the XM music channels. Some of the news/talk channels don't sound as good. And XM's in-house music channels sound best of all. Very good, indeed.)
Yes, many of XM's music channels are commercial-free, although they do carry XM promotional annoucements.
I think the channels that do carry spots are limited to 6 minutes per hour vs. 13 to 20+ per hour on local radio.
