I prefer clickies too at this point.
One, I am used to the UI more. (I have the tactical rotary) I would probably like the Executive rotary UI better.
Two, I only need 4 settings.
1 ultra low: when it is pitch black, you only need a little light
2 Medium low: for most applications
3 Top High: For what ever needs lighting up
4 Tactical strobe: Love nauseating myself in the dark and can't see how someone could stand it for long if they were approaching me at night.
The in-betweens of the rotary are kind of just extra. Nice, but I don't really need 12 to 24 increments of adjustment at any one instance.
I have had my rotary one day and just carried it in my pocket. I don't know what or how, but the rotary got a little crunchy from some kind of grit that got in it. It is out and gone now, but it was kind of unpleasant.
I could see how the Executive model interface that mirrors the clickies in ability to set 4 presets could be good, but one button has served me perfectly.
I love my rotary, and have been playing with it and am making it set up in a way that gives me close to what I have on my clickie and the rotary can take the place of 3 of my settings on the clickie with a press and hold for the strobe, but I think the KISS of the clickie is preferable.
