As far as shelf queens go, I have a Surefire E1W Winelight which I have carried alone in a suit jacket pocket in the past, for evenings out, but which I am loathe to scratch the burgundy non-HA-III finish on.
Regarding users, I don't know quite what to do with my Streamlight Sidewinder. It is a clever design in many ways, but the beam quality of the main led leaves much to be desired (will a Nichia 219 work with the optic?), and the other secondary leds are rather dim (which could be useful, I guess). What to replace the IR led with, a Nichia 119? I'm not in the military. The fact that everything is plastic does not necessarily bode well for heat-sinking, although it is probably well-suited to dropping on hard surfaces on a regular basis. I would love to turn it over to Milkyspit, but the gentleman is busy these days, and I wish him the best in catching up (and I venerate his talents).
