I'm not even sure the benefits have to be debated at the level of "tactics," even.
When you're used to shooting almost entirely with people who's routine shooting practices involve working from a holster, shooting while moving, observing 180deg. and muzzle-safe rules on a dynamic range, engaging multiple targets, reloading on the clock, and all that other stuff -- even the lesser accomplished "practical" pistol competitors are in a totally different class from those who are used to "square-range" shooting and bullseye type targets.
You can instantly tell the difference just by watching how they handle a gun.
