Carrot, that's comparing apples to oranges. The designed application is totally different. SureFire is primarily designed for short burst of bright light and small enough to not get in the way. Law enforcement usage comes to mind. They have tons of other gears on them, like gun(s), body armor, etc. They can't bust in a home with a cumbersome Thor. They can't mount a thor on their weapons. Just not the right tool.
Comparing a Thor to a surefire is like some guy saying "Yeah man, I can carry 3 tons of stuff in my truck, and that Honda Civic can't."
