As I had mentioned, I've been happy with my Fenix PD10. For those who don't know, it's a twisty 1XCR123. It has 3 modes, med, low, high but no mode memory. Max output is 180 lumen and min is 6 lumens. It's tough. The threads are smooth, but recently, the twisty switch has been a little flaky, not smoothly turning on and easily accidentally changing modes while turning on. I'm not upset, it still works well and has been on my keychain for 2 years.
However, I've been wanting to replace it with something with mode memory. I have a Fenix P2D as well. Essentially the same output levels, but with a clicky switch and starting at low rather than med level. However, the clicky is easy to accidentally turn on and it doesn't tail stand very well.
I've been looking for a replacement with mode memory and the ability to tail stand. As I've said, I prefer the brightness of CR123 and so that's a strong preference. NutSAK's thread got me looking at options again, and I finally pulled the trigger on a Lumapower Dmini VX:


It's a clicky with a well protected switch. It tail stands well and has mode memory. The thing that finally sold me on this light is that it is convertible. It will run on 1XCR123 or 18650 rechargeables. This is great for me since I have an Olight M21 that I run on 18650's and this gives me big flexibility on battery choice.
It's bigger than the Fenix brothers:


But not massively so in the 1XCR123 conformation.
I'm not very good with these beamshots, but here it goes on Max:
