My experience is definitely personal: most of my dives are either in a mudhole (Master Instructor) or in very cold, very deep, fresh water (Deep Trimix) scrabbling through wrecks. I've been diving since 1970 and get something like 200 dives a year in and pound my gear, so my experience is fairly broad. Personally, I currently own six sets of Apeks, a couple of ScubaPros and a handful of other stuff. I rely on my Apeks without hesitation. You have to seriously abuse them to get them to fail, they deliver a ton of air if you need it and breath as easy or hard as you want them to. I'm also a manufacturer trained tech for Apeks (also Aqualung, ScubaPro, Mares, Zeagle, TUSA, Sherwood & a few others) and I've seen thousands of regulators open on my bench. Apeks are a simple design, easy to service, hard to screw up and built like a tank.
I think you'll be very happy with your choice. There are other regulators that are as good or nearly as good but anyone looking for a high-performance, reliable, easily serviced, freeze and crud resistant...well, you get the point. They're monster regulators and my first choice.
