Looks like the Hollis has one D-ring on each shoulder, vs. two for the Dive Rite.

Personally, I didn't like having a second d-ring (which really surprised me).

Other than that, and the 3-point connection plate No Misses pointed out, they do seem to be pretty similar. I'm sure either is fine, and I get why you need the disconnect, given shoulder issues. Aside from interfering with where I want to mount my backup lights, I never really had an issue with the QDs on the harness.

The crotch strap looks a little odd on the Hollis plate... or is that just a pull ring for the shoulder strap?

My personal recommendation is, whichever you go with, don't bother installing the chest strap. I used one for the first 4 dives on my TransPlate, forgot to fasten it for the next 5 dives (and only noticed after I got out for the last dive), then decided to remove it, since it clearly wasn't needed. One less thing to futz with.
