A quick reaction, again based more on the aerospace industry than my not-as-broad-as-others racing experience...

Camlocks are pretty standard, and are "better" (judgment) in that with one twist/slam of the hand, from ANY direction, the male ends literally "pop out" - makes for a quick exit and reduces the chances of the latch grabbing, the link twisting, etc (has anyone ever unlatched their Skippy belts and still been "stuck"?). The latch/link approach requires you to pull from one direction to release....and, since the security of the system is spring/friction based (whereas camlocks are mechanically locked), they could suffer from mechanical wear....

However, the Camlocks are NOT able to be checked visually - i.e. you could insert the male end, not that get little "click" and voila, you think you're in but you're not. The latch/link is a system you can check "by eye" - which is why we used that system in (professional)diving rigs and in the "passenger" section of military planes.

Not sure if that's why SBRS picked them, or simply because they are cheaper.
