When the the calipers on my Avalanche froze up I replaced them with Powerstop units which basically were re manufactured stock units with slightly larger pistons and bored fluid holes. They do well with the added steel lines, the better pads, and the drilled/slotted rotors.
However on my go-fast cars, I've used Wilwoods a couple times and they are excellent. They make a set for the 2015+ SUV. As an added benefit they are about $1000 cheaper than ordering your truck with them or $3000 less since you don't need to buy factory 20" rims if you intend to put some of your own wheels on eventually. Wilwood makes a 16" rotor that requires a 20" wheel or bigger and smaller rotor for 18" wheels.
I can't see the quality of the SUV brakes being sub-par to the cars. The set I looked at for my upcoming burb purchase look almost identical to the 6 piston sets I put on my 87 Trans Am 20+ years ago and the set I put on my 00 TA back in 06. Since I have used 2 sets of Wilwoods over the span of 20 years and got more than I expected both times, I would expect them to perform the same or better with this upcoming purchase. Might be something you want to look in to.
