I think of snap shooting as a very quick shot--no pause at anchor at all. Like you said, this often leads to target panic and short drawing. To me, an out of control shot is just an out of control shot.

You nailed it on shooting style--the basics will be pretty much the same regardless--use what works best for you and don't worry about what the "experts" say. There are a lot of excellent shots that have completely different styles--Ferguson and Welch, for instance. I've seen these guys shoot, and they are good. Ferguson uses a modified gap system, Welch is "instinctive". I've changed/modified the way I shoot several times over the years--no one "right" way to do it for everyone.
