I suggest Eaton E-lockers for new installs. If you already have a dedicated air source, then maybe ARB if you do a lot of wheeling. If occasional wheeling, I'd still stick with E-lockers.
That said, I have ARB rear and Yukon Zip in the front with a dedicated small air compressor. Both have been flawless. The Yukon is essentially a copied older design from ARB. Then they improved some of the items that were problematic with that design. The Yukon has a better warranty than ARB.
