8 lugs are less likely to rip the center of the wheel out. the bolt ring diameter is larger and therefore closer to the outside of the rim which puts less torque on each bolt as the axle tries to turn the wheel, add two more bolts (8 vs 6) and you further reduce the loading on each bolt.
so yes, in terms of torque loading on the wheel and axle, there is a benifit to the 8 lugs.
depending on what kinda driving youre gonna be doing, the 6 lug may be fine, but ill let more experienced members tell you if you need the 6 or 8 lugs with 44's and whatever driving youre gonna be doing.
