"The key is to do some TESTS..."
My degree is in statistics, so I agree that you want to be careful about perceptions.
That said, from using both in dark shoot houses, my sense is that it isn't a close call. It's like wondering whether bald summer tires or new snow tires are better in the snow. Sure, a valid test would require running carefully crafted side by side comparisons in identical snow conditions and identical vehicles, with careful instrumentation to measure actual traction, etc, etc. But in practice, I think, the differences are dramatic enough that I'd be really surprised to find that the snow tires weren't actually better.
I took guns w/o any night sights, guns with tritium sights, and guns with lasers to the classes, and used them all. We didn't use shot timers, but the difference seemed less in speed - people shot at about the same speed with or without lasers[1] - but the accuracy at that speed was lots better with lasers. If you slowed down shooting with tritium sights enough to maintain the same accuracy as shooting with the laser, you were markedly slower. I don't mean 20% slower, I mean half the speed or less (n.b. I'm talking about 30 or 40 feet down a hallway here; at 5 feet where you aren't really using the sights anyway, the kind of sight doesn't matter).
Just my experience; YMMV.
(and, to be clear, I'm not presenting my experience as the be all, end all. If you've tried both and find the lasers don't work for you, that's fine. That wasn't the case for any of the people in the classes I've had, but if that's the way it works for an individual, it is what it is)
