For what's it worth in my drag car I had no change in et running 4.56 and 4.88 when I switched to 5.13 I picked up 2 tenths in the 1/8 mile. But your doing something completely different. I had a friend who had a mustang with a 5 speed and 315/35/17 had 5.13 and at 70 mph was turning around 3000 rpm on the street

35" tires right at home with 4.56 with a stick shift you could do 4.88 
with auto I would stick 4.56
stickshift gives you more control of your gear, so you can get away with more gear like 4.88

But this is really getting picky here, the difference between 4.56 and 4.88 is not much. 
Up until just recently they did not even make a 4.88 for the reverse rotation dana 35 carrier. 

What engine? 
stick or auto?
are you sure you will never want bigger then 35's? LOL
Is this going to be daily driven?
Why are we not talking about 5.13 ratio?

FYI the ring gear gets pretty thin at 5.13, 4.56 and 4.88 you will be fine. I use only Precision, Yukon or Ford gears sets....
4.0L Manual, Sorry if I didn't clarify that properly. I do want the slower crawl speed to some degree, 3.73 isn't doing it and well, the 3.08 just can't. lol And I've found in my research a lot from Richmond Gears, Yukon, and G2 Actually. 12* North has some options I been padding the wallet for. And actually, the Auto does ahve more advantages over the manual trans offroad and maybe even on road wise however, to me I drive the Manual trans because literally its more fun to drive than a "slush-O-matic" to me and makes for a nice millennial anti-theft device too..

And yes 35's will be the largest I need, at least on the 2 Ranger Rigs and for the Xterra 4x which will be sharing tire size, type, wheels, even bolt patterns so the (2) Rangers at some point will be converted to 6 x 114.3 so any of the vehicles go down while on the trail or were to suffer mass tire loss. All of the spares will interchange for simplicity and ease of carrying on. Within the trio at least two vehicles will always go and both on farther expeditions opportunities will have multicarriers on both vehicles and the trailers will be dual spares. which is an additional 6 wheels and tires. I know Overkill, but you'd have to understand the logic of it and the setup. Each vehicle will be its own with a spare but since the trailers will have additional fuel capacity in a different way, the multicarriers for the trailers will be dual spares. crazy I know but.. when you see the end results and setup.. It'll be more than impressive.., Promise lol
As for daily driven, yes mostly but neither myself nor the woman drive 90MPH anywhere anyway and if we had to, we have other vehicles for that. This "Trio" of vehicles are for literally special purpose eventually. I know, seems vague but no spoilers yet and 5.13 just seems over the top even for me.

Below is some compiling of my research based upon the current tire specs, but you'll get the point.











At 65MPH RPM would be 2574 +/- (4.88) a whopping 200 RPMS less @ (4.56) should be closer to 2405 - 180 or so RPM's less.. minuscule really but the shift points, and that little bit on both ends will help between low crawl-ability and some power delivery I think. Like I said, I'm not worried about top end - wrong vehicle.
