Because I don’t yet have a work bench, I like Ron’s bench. It is more of a “bench” rather than a “horse” (IMHO). I consider it to have additional functionality to the more standard “horse” design. But I plan to build something similar to both designs.
The additional functionality in Ron’s would be to use it as a mini workbench by sitting on the piece being worked or, using dogs with wedges or, hold fasts.
I like and see a use for both designs. In fact, I’m planning to incorporate several different design elements when I build mine.
Here are some of the resources I’m getting inspiration from.
