If ride quality is your #1 priority it's easy.
AEV lift. I've ran my DD rig 40,000 miles with one on 37s.
I've also ran the Rubicon and Pritchett canyon with the lift. ProRock 44 front and ProRock 60 rear with 4.88s.
I think the PR axles (at least the front housing) are necessary because driving stresses the axles and you want to be driving the rig and not have it in the shop all the time with repairs. You can spend time reinforcing the stock stuff, but in the end it won't be as good as going with the drive home option of the ProRocks. Plus the robust axles help the rig handle better on the road.
I know this because I ran the stock axles for a few weeks before swapping them for the ProRocks.
New driveshafts actually help on the road because they eliminate vibrations and you won't have to worry about the stock shaft boot breaking.
In the end you'll have a great DD that can do the toughest trails.
