I have been using a TLR-1 and I find it to be UBER reliable. Matter of fact, I find anything Streamlight has made to be UBER reliable.
I think everything SureFire puts out is an overpriced POS. On a good day.
That being said, I'm not sold on the weapon's light idea in general. I certainly don't oppose them, but I don't find them necessary day to day. Kicking in doors and yada, yada may be a different story.
I'm in the fortunate position where I've been able to kill tons of schit (legally) in the dark and I can tell you flat out that if you put a guy with a weapon's light against a guy wearing a headlamp, the headlamp wearer will win 10 times out of 10.
Having been fortunate enough myself to hunt at night, I had very different results than you did. Head lamps were for looking, gun mounted lights were for shooting. When I look through a scope, my headlamp isn't pointed where I'm looking. But maybe my head is crooked.
