Xm Satellite Radio or Sirius?

My mom's rent car is equipped with Sirius Satellite Radio. I have not had much experience with it before, but have fallen in love with it. I am considering getting a satellite radio put into my car.

1. Which is better, XM or Sirius?
2. Are they hard to install, by yourself?
3. Can I use it, even though my car has a "regular" radio and cd player already, albeit a error message sending CD player.

What are the differences? Do I need to pay a monthly subscription fee or buy loaded cards?
