Holster Type?

Which do you prefer, a holster with or without a thumbsnap or strap and why?

I used to prefer a holster with a thumbsnap. I hate holsters with straps!
However, after reading an article by Sheriff Jim Wilson about a year or so ago, I came to agree with his theory that the thumbsnap was just one more thing that you had to remember, if you needed your pistol for self defense. I now use either the Check Six or Askins Compact Concealed Carry by Blackhawk for my M&P's or a Bianchi Model 57 Remedy for my Kimber. None of them have a snap and they all employ adjustable friction retention systems.

Carrying concealed, the likelihood of having to fight for retention of a pistol is very slim. I'd rather have the quicker draw for when I needed it. Just my personal choice. How about ya'll?
