I thought the instructors were very good. The lead range instructor for my class was Brad Ackman, who was an instructor under Col. Cooper for nine years. They don't emphasize "war stories" at Front Site, but several of the instructors were active LEO. One of them was delayed for awhile, because his SWAT team was deployed.
I haven't been to any other training places, but I've heard that at most places, the instructors don't do any shooting. At Front Site, they don't hesitate to demonstrate when necessary.
Of course, there're two main goals to an introductory defense class: build confidence with gun handling skills; and all the ramifications and consequences of using deadly force for self-defense. Naish did all of the lectures, when I was there. He did a very thorough job of it.
