Have had a JM, JD is bolted to the floor (have had about 3 years now?). JM is great and is the best flowing game I've played not made by Steve Richie, but the abundance of modes, shots and a phenomenal artwork and sound package push JD way ahead of it.
Have not played BR much and the few I have the cannon was always fucking up. Cannon issues have kept me from ever persuing a BR, but it seems like a cool game.
Go JD. He is THE LAW
