I've got Swampfox, Holosun and Trijicon. I like the RMR for its lack of batteries and bulk. The 9moa green dot seems like it would be too big, but at pistol ranges it's really not. I pick it up just as fast as the circle dots on the Kingslayers and Holosun 507 Comp. I don't use an optic on my carry gun though.
