I think you are entirely right on that... I know I saw a site that gave the actual counts at one point but I've never been able to find it again. I did count on each image and they translate exactly to the correct ratios. That's probably why I've been dead set on 5.13 for so long because if 4.88 has the same pinion, what's the point of going shallower if the risk is all the same?So I believe this was true for the JK D44 axles, but I'm fairly certain the AdvanTEK D44's in the JL/JT all use the same 8 tooth pinion for 4.88, 5.13 and 5.38. Only the tooth count on the ring gear changes (39, 41, and 43 respectively). 4.56 has a 9 tooth pinion and the 4.10 picks up 10 teeth. Don't quote me on that as Dana has updated their site and it no longer lists the specifics for any ratio above 4.10, but you can count the teeth in the pictures lol. Agreed thought... you should be fine unless you are going crazy. In that case, take a look at dynatrac or currie axels.
