The 5.13 pinion is smaller and has fewer teeth. Which means less contact surface( fewer teeth engaged) with the ring gear.
In all actuality +90% of the members here don't wheel hard enough for that to come into play. Not everyone wants to climb a 3ft-4ft under cut ledge.

Love your setup skibovr. Looks great!
My setup:
AEV 2.5" w/ 35" Maxxis Bighorn on 17x9.
Auto 5spd w/ 3.73 on 3.6L Pentastar but plan to re-gear to 4.56 to keep my Daily Driver in the sweet spot and because I haul a camper and hit the trails once in a while. Lost a little pep w/ 35s but livable for now. Towing 3500lbs up Wolf Creek Pass CO is a tad ruff.

4.88 39-8
5.13 41-8

Other way around....
5.13 if wheeling....4.88 if not....
And with the Pentastar and Expedition style Jeep (with trailer) on 35s:
4.88 if you're wheeling, 4.56 for more highway mpg and still a huge bump in torque over 3.73.

If he wants the jeep with the best performance on the road he needs to run 5.13's. If he's wheeling he should go with the 4.88's to get a little stronger R&P. This is my Opinion, I would never gear based on MPG, if I cared about that I would have bought a VW turbo diesel
