The best regulator on the market......is the one that makes you happy to use!
I have 5 regs, by three manufacturers, and they all work just fine.
Do I have a favorite, it's a toss up between my Apex ATX200 and my Mares Abyss. Both perform very well at any depth, and I have used both to depths well below recreational levels, in water that is 3c .
If you think you have tried enough different regs., by different manufacturers, in enough environments, to lead you to this choice. Then well done and move forward with the purchase.
If you have doubts about it in any way, then keep looking for a while. If you keep coming back to this reg, then the choice is clear. The bottom line is that what ever choice you ultimately make, someone will agree with it, and someone will not. But neither of them matter, as long as you are happy with the choice.
