There are 2 interactions occurring at the wheels that determine traction: 'simple' friction, and the more complex interaction of the engagement of the carpet and the tread. The former is dependent on the normal force applied on the driven wheels and the coefficient of friction. The latter is dependent on, among other things, contact area of the driven wheels.

The driven contact area will roughly be the same for both configurations (six wheels worth of contact), so the maximum traction from that interaction with only the centers driven is AT MOST as high as that as when all wheels are driven. Traction from friction will (almost) always be less when only the centers are driven. So, as far as traction is concerned, all wheels driven is preferable.

I don't know how it would help with turning, but you could test it if you have time to see if there is any improvement.

Now, traction and turning aren't the only factors involved. Weight, reliability, and maintenance should also be considered. When all factors are accounted for, it might benefit you, or it might not.

Another option is to only drive the middle and back, and shift your weight rearward. Assuming the center wheels are lowered, the front wheels would usually be off the ground so your traction would normally be the same as it is with all wheels driven. there would be brief periods where the traction is reduced, but it during forward acceleration and pushing (when it is particularly important) it would be maxed out.
