I run a Mtroniks Truck controller, and it is pretty awesome. My favorite thing about it is that it's WATERPROOF. The external soldering bars (or whatever you call them) are also pretty nice.

I also run a MGM Compro 12012 new version, and I like it much better than the old version. The main difference between the new/old is that the new one has the "freewheel" option that corrects the problem where the controller changes the motor RPM to match the throttle input. It also has an adjustable drag-brake setting. The newer ones also have reverse disable.
The programmability of the MGM controllers is better compared to the Mtroniks. There are more options for acceleration speed, braking strength, Lipo cutoff type, etc. BUT, the MGM ones (at least not the plane style) aren't waterproof. IMO, that is the biggest drawback to them.
