I was running some numbers this morning. I found a handy calculator to help you make comparisons.

Superior gears are were the first developed to fit the new jk Dana axles and usually considered the best for this application.

The negative comments are from guys with 6spd's. BIG difference in the gearing needs between the two transmissions. Since you have an auto, you're good to go.

4.88's will be perfect on a JK, the 5.13s are over kill unless you plan on going up in tire size in the future....IMO

If you have 35's then 4.88, 37's then 5.13, if less than 35 then you may as well leave it stock. I have an auto with 5.13s and 33s and it runs great!

I have the 6 speed and planing on ordering 35s, but I will use if about 80% of highway and 20% offroad, so are 4:88 still the right gear? I was thinking 4:56 which would put me back at stock performance.
