As background, I have never taken the rescue class -- perhaps I will some day. But, I have been diving for a few years, with a few dives under my belt. Cold water and warm water, wetsuit and drysuit, good viz and bad, shallow and deep, day and night. I have also made and/or assisted with a few actual rescues and, in my younger years, had a lifeguard certification.
And I still have a harness exactly like you use in my garage. I used it for many dives and it served me well. But, IMHO, there are much better alternatives. And, in the scheme of what one spends on diving, just not that much more money (maybe another $100?). I find the DUI to be a much better product and worth the extra $100.
At the surface, I like being able to just pull a yellow handle if the crap really hits the fan -- no worry about crotch straps, harnesses, etc (when I was certified, everyone wore crotch straps so I am practiced at using a regular belt and stap). Have I ever done that other than during a drill? No. But there may come a day...
The incidents I have been involved in, the person absolutely just froze up on the surface. No thrashing but also no helping. I really really like the yellow loop handles then. Plus, if they are responsive, you can direct them to use the handles. Yes, you can get out the shears but this is better in most circumstances (I would use shears near an exit point or boat with a non-responsive diver and just cut off all of their gear).
Now, lets talk about Darwin type scenarios. While these seem absurd, they happen more than one might think. A frequent poster (not me) used his pony bottle three times during a week of diving in Cozumel -- so Murphy happens more than most would think. Perhaps more with some people than others but none of us are totally immune!
Here is the scenario: You are really excited as a whale shark just went by (or you are seasick and want off the boat now). Because of currents and big surface swells, everyone is directed to do a negative entry and meet on the bottom. You turned on your air, but the DM, as you were going in the water turned it off (this has happened -- or you just forget to turn it on). Turns out you are also weighted a bit too heavy. You take that first breath and find nothing. Switch to your octo. Nothing. Your lungs are starting to scream for air and the surface now looks far away. Easier to start fishing in your weight belt pockets one by one? Get out the shears? Do a negative ascent by swiming hard? Or pull a big yellow loop? Do you worry about DCS at that point or drowning?
