We may have different standards, ( 1/8" diameter "aircraft cable" or wire rope, is rated at 2,000 pounds static load. Usually get a 3-4X leeway vs. actual breaking point, ie: it will break at more like 6,000 pound load.. I'm not sure what the practicality of that kind of strength is for carrying a camera.)
... but it seems to me there are many very good solutions out there.
I prefer one of the more affordable options in today's market. Once highly regarded as "the best", but these days there are FAR more expensive options,.. I don't know that any of that additional cost makes them "better"
Optech is what I have used since about 2003.
I use some variation of the Optech pro loop system 100% of the time.
This includes all my neck straps, a dual harness, and a sling. Also the long lens strap on my 500mm Prime.
I've used the Optech's with heavy pro wildlife gear on 4 continents, in the desserts of Namibia, in the rivers of the Okavango, in the Andes two miles high in Peru, and on boats and islands in the Galapagos. I have never had a failure.
20 years ago, this was the best. These days people are seeking out steel and leather, but frankly those solutions are a lot more "old school" than neoprene, and a lot heavier and less comfortable for slinging 18 pounds of gear around your neck. The plastic connectors on the Optech will last I assure you.
