Might be that you were confused by my brief wording. What I mean is that on each side of the robot, the two wheels on that side will slip about the same amount, so you can implement slip control on a "per side" basis, instead of a "per wheel" basis.
Hope this makes it more clear!

The side will slip when the wheel with the least amount of traction breaks free because once that happends all of the torque from the slipping wheel will go through the chain to the non-slipping wheel and that will cause it to slip as well.
Thus 4 independently driven wheels will be slightly better ... although with traction control you may be able to compensate for the differences.
