It's better than an auto locker, but they are not fully transparent like an open diff.
My $0.02 is that selectable lockers are the only thing safe for front diffs on snowy roads. That's a personal thing, some people are comfortable with limited slips.
I decided to sell my Air Lockers because in the front especially it took up quite a bit of volume in the housing and didn't leave much room for lube (less than a quart IIRC). I don't do enough rock crawling to see the benefit of a front locker but do spend a lot of time in 4WD high and in 2WD with hubs locked.
