I find it to be a toss up between:
1. Fenix PD 32 UE
2. Nitecore E 25 Cobra
Both are small, long battery life, able to start at low lumen but go up to a nice 700+ Turbo mode. Neither are perfect, however.
The Nitecore has a blinking light to be able to find it the dark but it does not have a reliable clip. It has a signal to give you the battery strength, a feature I love.
The Fenix doesn't tail stand, but has a strong clip and a very nice sized diffuser cap which it comes with.
Both are well made. If I could combine the two of them...
I call it my
Fenicore PD25:
Small length like Nitecore
Thin like Fenix
Powerful yet versatile like both
Tail stand like Nitecore
Blinking light and battery strength indicator like Nitecore
I think, perhaps, since it is "my" light, I will make it have a LED display like the TM 26 and add in an internal charger to plug it in!
