I don't own a JL, and so this is second hand, but take it for whatever it might be worth. I have a buddy who has had built Jeeps for years. Runs 37's, had been through multiple re-gears, etc. He now drives a 2019 JLUR with the 2.0/8 speed/37s. He has not re-geared, and he says he does better than his buddies who have the 3.6/8 speed, 35's, and 4.88s in the mountains. He has almost as much money as God, so price is absolutely no object to him. He has no intention of re-gearing his 2.0.
That said, I'm thinking that his little turbo 4 is working hard--might be a great choice for a 50-75K miles before upgrade vehicle, but I'd sure think twice about it for a 200K vehicle.
