I can speak from experience. When my CoachNet expired, I shopped around and decided on Good Sam Roadside Assistance (Platinum), early this year.
I had a blowout during the summer (see my other thread). I called Good Sam. They were extremely helpful (esp. considering this was July 4 weekend) and had me back on the road in about 3 hours. They had a service man come out from the nearest tire center, change my blown rear tire and gave me one new tire at NO COST!
So, I highly recommend them based on this experience.

P.S. - they even have an App!
