I voted "no difference" although there are more pro's than cons. The only reason I voted the way I did is because I don't use one because my "loop" is on my release. I have shot a rope release for 30 years now. It's easy, I'm familiar with it, and it's one less thing to mess with.

One other reason is that I don't care for wrist/caliper releases and they are the most common ones used.

My preference may change one of these days now that Spot-Hogg has introduced the "Saturday Night Special". Remains to be seen yet.
