The bandwith on Sirius's 3 satellites still have less than the bandwith on XM's 2, and from what I read and XM may have launched another one recently (but I can't confirm it). Not to mention the ground loopers, which XM has many more of.
I actually don't believe that is true about the satellites having less bandwidth, but I can't find out much information on how powerful (that's the key point - not bandwidth) the Sirius satellites are. The XM satellites transmit at 10 megawatts.
XM's satellites are in geostationary orbit at the east and west coast above the US while Sirius' satellites are in geosynchronous orbits allowing each individual satellite to be over the US for 16 hours. They are also placed higher in their orbit to allow better coverage which is why there are less ground repeaters.
You can listen to Sirius on the web, which makes having a unit in your office pretty moot.
Of course, it's up to someone to purchase what they want. I don't listen to comedy or howard stern, but I listen to the rock stations on Sirius and I can't complain because it has loads of music and consantly updates with new music. When I did listen to XM which a friend had, it was a constant barrage of repeats.
