Heres an eventual contribution to this thread!
Disclaimer: a) I don’t use this light as keychain; b) I use a Rovyvon light as keychain and as a neck light and…they will be hard to beat for me! Still, I am open to this thread’s development!
This is the DQG Slim Ti in it short format. It takes a 14250 (half size of an AA/14500 cell) and 1 or 2 AA / 1x 14500 batteries when using extension tube(s), has 3 modes, no memory, XP-G2 on the rosy side and a TIR (originally was narrow beam, I modded and put a pebbled TIR).
Compact, bigger duration than an 10880, just probably larger.
Driver and LED come together, switch is replaceable, doesn’t have integrated charging, batteries are replaceable too!

Later I can compare it with some other keychain lights in terms of size and output (using an AA cell, as I don’t have any 14250, yet)!
I can tell that it is smaller in length than a RovyVon Aurora A8U…
