eh, yes and no. When it comes to selectable lockers, I would probably give it to ARB being that when it's working right, it always works and right away - ON or OFF. This is not always the case with e-lockers. If there is hesitation in my voice, it's because when they are NOT working right, they can be totally useless.
For instance, when the air leak in the locker is bad enough, it simply will not work. If you melt or cut an air line, something that is common, they will not work. There are things you can do to help the later like installing braided stainless steel lines (something I always do) but there's little you can do about an internal leak short of taking everything apart to fix it.
That said, I do need to point out that I've ONLY ever had a problem with my Dynatrac ProRock 80 ARB. The PR60's and PR44's I've run in the past with ARBs have all been great.
