I've had exceptional wear from the BFG all terrains. However, I've had good wear and drivability from Bridgestone, too. I'd check the durometer rating, traction, etc. to establish the characteristics of the tire. A higher durometer rating can be indicative of increased tread life but have a lower wet traction. The heat and traction ratings can be used to look at 'perceived' value. I had some Cornell tires from Pep Boys that I put about 60K miles on; I ended up selling the set of tires and rims for more than I had paid for all 6 of each.

A little bit of internet research coughed up the Sport King, Mud King, Traction Plus and All Terrain names. It could be that Cavalier is just an umbrella name for other mass produced tires. I've had and some Sport Kings and Mud Kings with good service.
