I have used Scubapro almost exclusively for 18 yrs, and I agree even the low priced regs are good performers and are very reliable.
I have tried a Genesis reg and have owned a few Dacor regs and a US divers reg but have never kept them long. They just did not seem to be up to the same standard as the Scubapro regs I have owned and my wife and son both agree with that sentiment.
Much of this is subjective and related to the "feel" of how the reg breathes, but in my opinion that is important.
Scubapro also offers excellent warranty and parts support. I can still get parts and service for 25 yr. old Scubapro regs. In comparison, Dacor discontinues parts in a relatively short period of time making servicing of an older reg problematic and dependent on dwindling dealer parts inventories. Over the years I sold a Dacor 600, a 900 and a 960 which is a good thing as none of them have parts support at this time.
Scubapro regs are a little more expensive, but dealer support and service is good and parts are free under their warranty program. They are also very good about offerring upgrades for older models which further extends their useful life. You pay a bit more upfront, but I think you more than make up for it in the long term.
