All of the torque? or the difference in torque between static and dynamic friction?

Thus 4 independently driven wheels will be slightly better ... although with traction control you may be able to compensate for the differences.
I agree that you can get a bit better traction with independent 4wd, but I also think you can do a lot with per side traction control.

In our case, we're using up all the motors on the ball handling stuff so it's a non-issue, we only have one CIM and one tiny Mabuchi motor (and the window motors) left for each side of the drivetrain.
