As you note it's situationally "all of the above" but I think the high compressed ready appears most flexible to me. But to keep the muzzle discipline I'd use anything including Sabrina which I was fascinated to read on these pages that Kyle DeFoor taught for running.
I raised myself in the late '60's through '80's on the low ready from the Modern Technique but concluded the positions that pull the gun in closer to the body are better all the way around. Because there's so much more involved than just shooting. That's my take..
