Once again, ARB, there simply isn't any other locker that works as smooth and reliable. Some folks hate them...fine.
I'll still recomend them to even those folks.

Here is a factor for you.

If your ARB has any sort of warranty issue, ARB can sell replacment parts and guide you/shop through the repair.

If an OX or Eaton or Ected, needs repair, they all require you sending it in to their service dept, and however long a wait to get it back.

Seems simple to me.
