I think I'd pick the ones from ICON and 4WP in this case before Camburg. The ICON and 4WP arms benefit from the rebuildable ball joint (ICON calls it the Delta Joint, forget what 4WP calls it) at the end of the arm. These joints have really revolutionized aftermarket upper control arm tech (in my opinion) because they combine the best features of a regular ball joint (long life, low maintenance) and a uniball (lots of angular misalignment). Uniballs have a limited life in a daily-driven rig and have higher NVH compared to the Delta joints/balljoints). Camburg also uses SREs (heims) on the frame pivots while the ICON and 4WP arms use some variation of a poly bushing with some reinforced metal pivots, it appears. The poly bushings will give a little more cushion than the heims too.
The ICON/4WP arms appear to be very similar in design. Not surprising, since the lead 4WP suspension engineer (one of the BEST in the industry) used to be the lead engineer at ICON (he designed/patented the Delta Joint while working at ICON).
