My wife and I have the Delta4/FDX10 setup.
We are not into tech yet, but working on it. We got in almost 100 dives in our first year of diving. Most of our dives are in the great lakes, cold and 100+ feet.
We have never had a problem with our regs to date. We took a vaca to Maui and did some shore diving in really high surf. Ended up getting stuffed by some waves and got sand in ever crack you can think of. Rinsed the sand out of the 2nd's and finished up a week of diving. Had them rebuilt when we got back and they still had some sand, but worked perfect.
We have done shallow dives in the Niagara with 40 degree water temps. I over breathed the reg to try and free flow it until I was dizzy and it did not free flow.
Here is another ScubaLabs test that has the Delta4 in it with the same tests as the above posted link. The Delta 4 scored right along with the Apeks.

I understand the opinion to use what works and don't fix what's not broken. But except for the swivel as far as I can tell the Delta4 meets all the DIR rules. You can easily remove the swivel with a fitting change when putting on a long hose.
We are also looking at getting our tech gear started. I was just going to buy a second set of Detla4's for our doubles. But if someone can point to some info of issues I will rethink that, and something more than "there not reliable".
