Detroit is a far superior locker as far as mechanical lockers go.Thats my opinion only and not to be taken as gospel.They have been around a long time and Ive yet to here any complaints.They will freewheel around corners and lock up tight when you need em .Your lock rite is the easiest and fastest way to get you going and unless you are a full time rock climer you should have lots of years with it.and see if you can full time lock those hubs in the future. The ARB is a good diff ,gives you the benifit of a stock diff and you can lock it up whenever you wish which makes it appealing for the front axel also .Down side is price for both and the ARB requires the compressor.
