I’ve owned both. While I like both I prefer the clicky. I like the clip options along with the tailcap is easily user replaceable and can swap from flush to raised tailcaps easily, I’m around a lot of dirt at work and I felt the rotary could be a potential long term issue if dirt and debris would accumulate inside the ring
That's fair. I don't necessarily mind about the lack of a pocket clip (okay, maybe a little) but truth be told I do like the look of the light more without one. - I'm intending on just throwing it in my pocket. I usually like to conceal anything that MIGHT be able to paint you are having a firearm on you, and somebody seeing a knife and light clipped to you pants pockets a decent clue that guy is either a cop or CCW holder. (At least here anyway)
I am not ever in dirty/dusty environments. So I am not worried about the longevity of the rotary in that regard. With that said, that is 1 HUGE benefit of the clicky, and you nailed it, that it's user serviceable. Thats actually the MAIN thing that was making my decision between rotary or clicky a little difficult. Reason being is because I've done a lot of digging and MOST of the time, people who do have an issue or need to send back their HDS seem to have an issue with the rotary itself. Then again, the amount of people who have used rotaries for YEARS, and have never had an issue HEAVILY outweigh the few that have by a tremendous margin (by the looks of the endless threads I've gone through at this point).
To your point about Switching between raised or flush tail cap button. That is not a concern for me, sure I guess it's nice to be able to do (I guess?) however, I think most would have a preference and just roll with that type not change constantly.
I think for EDC flush would be beneficial especially with it being thrown in a pocket or bag. Nearly impossible to turn on accidently. Not so much with a raised button though.
