What we tend to find is that depending on the nature of the individual's assignment/duties...different UI and different beam patterns, form factors, etc, are favored.
If you patrol a railroad yard and need to flood the yard before the hobo with the handkerchief on the stick has a chance to hide, you hear a noise, and want the light to go on in high, period...and flood the place....and that high might need to be 1000+ lumens.
If you need to search a car, or read a map, that one 1,000 lumen light either needs a low, or, you need a second dimmer light that won't glare you to death at close quarters.
This is why so many like the Klarus UI, you DO get one button for on/off...and it ONLY comes on in HIGH....simple. If you want less light, you hit the other button...again, easy. Turn it on again after it had last been used in low, and it comes on in high...like always...no memory, no scrolling, etc.
People who don't NEED a lot of light, ALL they do requires 100 - 200 lumens, etc...can get away with one level, "ON"....and, then, "OFF". This way, they can't screw up....they also never have to scroll, etc.
Guys who patrol with a light on want it to be able to click on/off one handed...if they have to hold a momentary switch on for hours on end, their hands would cramp up, etc...plus, if the sheite were to hit the fan, and they had to turn the light OFF to avoid it being used as a target beacon for a bad guy...they do NOT want to then have to take two hands to TWIST the cap, etc...to unlock it.
The guys who are using the light in short bursts...or to enter a prospective fire fight, etc...they CAN afford to hold the momentary button down during the entire engagement....as its worth it to simply be able to let go to turn the light off in a hurry.
So one group using the lights for a long patrol hates twisties, as if they need to turn the light off, they must sacrifice the gun hand to use it to do the twisting...and they don't want to hold in a momentary switch for an entire dark patrol either...so a simple, intuitive on/off click works like a charm.
The other group tends to be afraid that they might forget to click the light instead of letting go, MOSTLY guys who ONLY HAD momentary/twisty lights..and are conditioned to let go, not to click.
If you learn on a clicky, the clicky is natural...if you learn on a momentary, then that seems natural, etc....its what works for you.
Generally, NO LEO's I know want a light that you have to scroll through modes to get HIGH, EVER.
Non-LEO's HATE lights that come on in high, because they typically want a little light to see where they dropped something, or to not bump into stuff, etc....so most lights out there are available for the masses with low-med-high orders...instead of High first.
Compare the LEO's writing tickets and patrolling warehouses, parks/large dark areas, who depend on flooding an area to see all the perps and where they're hiding at once, to the ones in essentially combat situations....and you get into the preferences for a tight beam with no spill to illuminate your position/the guy next to you...and more or less just put a circle on the perp to aim at.
One group's lives depend on NOT having to sweep a small circle of light back and forth to stitch together what's out there..they want DAYLIGHT - NOW!
The other group's lives depend upon a small circle of light to provide an aim point.
So, just like a jeep guy will scoff that the Porche can't even climb a curb, and the Porche guy will scoff that the jeep would flip over if it cornered at a walk, etc...the LEO's, etc...will all have reasons why THEIR light is best...and it might be, for them.
So its always interesting when you see what is in the field....there's always a method to the madness.
:naughty:
BTW - This is the moral equivalent of patrolling in the old days with a pearl handled revolver:
This is a work of ART!
