At this point in the history of modern diving, regulator designs have been pretty well tested. There is not a lot of difference in recreational performance between the top models of the top selling brands as most never work hard enough to really push the regulator's air delivery design limits, the only other discriminator in rec diving is cold water reliability. The Military, working divers, and tech divers will see a difference at the deeper depths they dive and workloads. The real differences get slightly larger when you look at initial cost, maintenance costs, parts support, and long term reliability from various manufacturers. Scubapro established better performance back in the day, but now that patents have run, we we benefit from competition. I like my Scubapro regs, but the downside has been some impossible to deal with dive shop owners for maintenance over the years. Now that Atomic has some history I have options for alternatives of equal design and performance.
