Personally, I would consider the smaller cams if the rear gear ratio was less than optimum- like low 3's or high 2's, and/or OD tranny and/or tall rear tires. You would notice the increased torque especially when taxing the truck- pulling the loaded trailer, for example.
Otherwise, I would stick w/the 268 cam.
