For one, I can't use a grip like you guys use, having crushed my hand in my youth. However, I get cleaner release as well as better ability to draw heavy bows (not that I'm there yet) and it lets me pull some awesome tricks like holding two arrows in my draw hand while firing a third, and nocking them as fast as I get one off the string. That's a required skill for horseback archery, and occasionally wheelchair archery is like horseback archery.
