Both are good products. Both work wonderful on the trail. In a longer vehicle one could consider price to be the deciding factor. In a 40 where drivetrain length is a major issue I really believe the Rockbox is the sweet unit.
With the SBC and AAs rockbox the crossmember stayed in the factory location with no mods. The stock speedo and E-brake cables fit fine. Best of all the stock tranny hump went back in with only one simple hole added to accomodate the new shifter.
