Stargost,
There are lots of threads asking questions like this and in all my reading of these forums, if you read between the lines, I have discovered this: Almost all those who have used both an Atomic and any other brand, always seem to say they prefer the Atomic regs when compared back to back. The Atomics are also consistently rated very highly in every test I have seen, especially in work of breathing. It seems like only those who have never used the Atomic are the ones who are quite happy with their current reg, whatever it may be. Having said that, all the regs these days are pretty good and we are splitting hairs to make a decision sometimes. I have nothing against any reg maker. But for me, I want the best reg I can buy for me and if it costs a couple of bucks more, I feel I am worth it and that is a small price to pay IMHO.
It reminds me of the guy who drives a domestic car their whole life and tries to argue it rides and drives just as good as the premium brands, without ever having driven one of those. Then some day, perhaps 20 years later, they eventually get a chance to take that BMW for drive and discover, gee their really is a difference. You get what you pay for IMHO.
Again, it is your life, use whatever you like. All regs are pretty good as others have said. My opinion is certainly no more valid than anyone elses. Maybe my opinion as a brand new diver should hold even less weight than average. But that is for you to decide. But I want the best equipment I can get for my money and am quite happy with what I chose for me. This is just the point of view of a newb diver who is investing in Atomic regs for the reasons above and those previously stated in this thread and my own research. Best of luck in your decision and safe diving to all.
Mike
