I am with this. I have used both. Although HOG works just fine, AL is overall manufactured to higher quality. . . .
In what aspects do you see differences in quality that would make a difference in practice? Do you have reason to believe HOG regs fail at some point due to lower quality materials or something like that?
When I was facing the OP's decision, I went with HOG. My reasoning--right or wrong--was that a reg that is in substance the same thing sold under various different brands must surely be a tried and true design. And I can service them myself after taking a course, saving thousands of dollars over the years. That appealed to me.
Without much hesitation I would have spent more money on a premium brand, but when I asked on SB whether a premium brand is worth it, I heard nothing that led me to believe HOG is inferior to other brands in any way that would affect the kind of diving I do. Nobody said they break after a while or something to that effect. All the sensitive little parts are replaced during service, which I do myself. Maybe if one is doing extreme depths or under the ice or something, that might call for a premium reg?
A few years ago, HOG was all the rage here on SB. I suppose if the price difference for a premium brand is too small to pass up, then get that, but even then, I don't clearly understand why the premium brand is better.
