^ Not exactly correct, Tim. Sirius does have three satellites & they are in a geosyncronous orbit over North & South America (that means tey move in a figure eight pattern) so at least one is always over North America.
XM has two satellites & they are in a geostationary orbit over North America (East & West) that don't move but two satellites are always focused on North America.
The difference being that Sirius' orbit reaches more to the north (meaning Canada) so currently they have a better signal angle. As defro13 mentioned above, once XM is turned up & their repeater antennas are operational it'll come down to whether Sirius' programming is worth the extra $3 per month.

geosynchronous - of or having an orbit with a fixed period of 24 hours (although the position in the orbit may not be fixed with respect to the earth)
geostationary - Of, relating to, or being a satellite that travels above Earth's equator from west to east at an altitude of approximately 35,900 kilometers (22,300 miles) and at a speed matching that of Earth's rotation, thus remaining stationary in relation to Earth.
