If you've already made up your mind, go with ARB.
He mentioned that he does go offroading, so like any of us, he wants more ability.
I do however get in the mud and snow off road and do some desert trails and washes with moderate terrain. I'd like to know that I have as much traction as possible for the Jeep in it's current set up.
Well, the important distiction is that a Detroit Locker isn't a "full time locker". It just isn't selectable. You just don't get to exactly choose when it locks. The only full time locker is a spool, meaning you have no differential. I drive with a Detroit Locker every day through a city and it's not bad. The only times it acts up is when I take sharp turns. Sometimes it does not want to disengage and I have to drop the clutch in and out. Choosing just the right gear in turns is important also or you get some bucking. The key is learning how to get it to disengage. It's not a full time locker, however, so it will disengage. The key to an auto-locker is that if you are accelerating or decelerating so that there is some stress applied against the axle internals, the locker will lock. Otherwise, it will act as an open differential. You can learn to control this. It takes finesse.
I haven't yet driven it on snow, but I have been reassured that it will be fine in 4WD. That remains to be seen. Do *not* use an auto-locker in a front axle when things will be slick, however. Your Jeep will crab-walk.
