If money grew on trees, brushless would be the way I would go. With the right gearing you'll have enough torque to everything in the drivetrain. Same for speed........stupid fast ! If you're on a budget, like many of us are, then the stock Titans are hard to beat. If you feel like playing around with some larger brush-type motors, check out some of the motors they use in cordless drills. Ever check out the torque of a Dewalt drill ? It's got plenty. Anyways, good luck and enjoy.
