why is it so hard to find a high quality 18650 light that I like?

No problem.

I vote for you to get the ZL SC600.

I have been EDCing it for a few months now. It is the best flashlight I own.

When the neutrals come out, I will have two SC600s.

They're afraid it would be the only one you'd ever need to buy...

"I really want a high quality ~100$ light that runs on 1 18650..everything I look at it has a downside..ie: not bright enough, not enough throw, bad UI"..

Totally +1 on that. The more I research and shortlist the more frustrating it gets. This thread's got me seriously looking at the ZL SC600 now; if only I liked the UI more..
