Between those three, and just about every other comparable regulator on the market, I seriously doubt you'll notice any difference in breathing. Likewise, weight doesn't really make much of a difference underwater. If your regulator is uncomfortable, it can most likely be dramatically improved with a different mouthpiece. Titanium offers a weight advantage, but it's not enough to worry about for the average diver. Titanium is also better at corrosion resistance, but again, most likely not an issue. I've got 3 regulators at my house. First one is 20 years old, second is 13 years old, and 3rd is 3 years old. All three look great. 1st one is mostly out of service, but the other two get serviced regularly, and corrosion hasn't been an issue.Now the question that I can’t solve on paper. How much difference there is between these quality/premium regulators when comparing comfort and especially ease of breathing, at recreational scuba depths?
Is there a regulator that clearly offers better performance or comfort, aside the light weight of Atomic T3. How do SP G260 and A700 differ? A lot of people tell G260 is the easiest breathing regulator, but scubapro advertises the A700 more in this respect.
If I were buying those, I'd most likely go with the Apex. But reasons have nothing to do with performance. The Scubapros would not even be considered. Nothing at all to do with performance, or really even Scubapro. It's just that I absolutely hate the Scubapro dive shops in my area. I refuse to set foot in most of them, and would not be willing to have service done at any of them. I can get Apex and Atomic serviced at a shop I like. Same place that currently services my Zeagles. Since servicing the two is a tossup, I'd go with Apex on cost alone. There are cheaper Atomic alternatives, which breathe exactly the same, and could make the decision more difficult.
