Ya I know traction control pretty well. I was just wondering how good it is on the rocks, or why a front locker is better(what specific sort of situation is a locker better).
Of course it's just like any traction control except that it doesn't reduce throttle... I didn't know about that...

The easy answer...Yes and No
Do you want both tires spinning with a 50/50 split of power in the front or do you want one tire spinning faster than the other, thus getting more traction on one side as opposed to equal on both. If one front tire is in the air ATRAC should do fine by trying to lock up the tire in the air so the tire on the ground gets traction. If both tires are on the ground and traction is poor, the locker would do better.
A locker makes the vehicle a true 4x4. Without a locker only ONE tire spins on the back and ONE on the front (i.e. gets full power). As the powered wheel slips the power is transfered by the diff to the other tire. With a locked diff both tires spin with full power at all times which equals lots of traction. This can be good and bad at the same time.
ATRAC has to slow one tire to power the other, it fools the diff into thinking that one tire is slipping more than it really is. ATRAC is an old trick used by setting the hand brake with a Posi in the rear that would make it like a mini-locker (a very poor one), same concept new package. I used to do this in my XJ and drove over everything basically with open diffs.
With ATRAC on and the rear locked you should have no issues crawling over anything with exception to very extreme stuff. Rely on your skill over the hardware and you will be better off. The real question is how do you navigate over something that is slippery without the aid of a traction device when you need one.
Did that answer it or am I way off?
