I personally like ARB and Detroits. I notice your location is way up in the North, and if your Jeep is a daily driver, Detroit lockers are a bit dangerous in the snow and ice. Detroits are actually awesome, but not very "refined" for street, daily drivers. I run ARB's front and rear now on my daily driver and absolutely love them. Two things to know if you choose an ARB:
1- make sure the shop doing the install has completed dozens (or even more is better) of these, and see if you can research locally any reviews of their work for reliability and customer satisfaction. ARB's seem to only have failures in the axle housing when the set up was not done properly by qualified shops. Sounds obvious I know, but just because you own wrenches does not make you a qualified installer
2-maintenance, if the install in the diff housing is correct there is not much to do there. The air compressor however will require a tad bit more servicing. Cleaning little pre-filters, keeping contacts on the electronics clean, and a few spare solenoids on hand because they do go out occasionally.
Not trying to scare you off from one of off roads best lockers. Most guys just will not tell you that there is some pros and cons about ARBs, but they truly are worth it if done correctly.
