Thanks to all the folks for their suggestions and recommendations, and especially to reppans for answering my numerous questions. Looks like I've found my new EDC: QPA-G2 on a 14500 (actually a QP2A-G2 head on 1xAA body, since it seems EVERYONE is out of the QPA-G2). Just got it today and have been testing it against the other lights (unfortunately, it's still daytime. Can't wait for it to get dark tonight).
For anyone interested in something similar, on 1xEneloop, the QPA-G2 is noticeably brighter than my old Fenix L2D Rebel Head on L1D body. While the Fenix's hotspot was visibly brighter than the Zebralight SC80's hotspot (the Fenix's hotspot is visible within the ZL's hotspot while white wall hunting), in actual outdoor use, the SC80 puts out so many more lumens than the Fenix, the difference was not really noticeable. The SC80 just lit up a much bigger area. The QPA-G2's hotspot is brighter than the Fenix's (and SC80's) though, even when they're all on an even playing field, running freshly charged Eneloops. On a 14500, the QPA-G2 is quite a lot brighter.
The QPA-G2 on 1xEneloop has a brighter/tighter hotspot than the QP2A-X on 2xEneloops. It also appears to throw better when comparing on my kitchen wall. QP2A-G2 vs. QP2A-X, both on 2xEneloops, the G2's hotspot is definitely brighter. Unfortunately, I'm not sure if the G2 is brighter on 14500 than it is on 2xEneloops since I can't test that side-by-side. The QP2A-G2 head on 1xAA body running a 14500 DEFINITELY has a brighter hotspot than the QP2A-X though.
Unlike the Fenix (and a myriad of other 1xAA lights) which direct drive their LED when run on a 14500, the QPA-G2 does retain all modes. I have noticed one odd thing about the QPA-G2 on the 14500 though. If I turn the light Off and then On anytime sooner than 20 seconds, it appears to 'memorize' the last setting and register the On button press as a mode toggle. Eg. if I have the light on Turbo, then turn it Off, turning it On again before 20 seconds have elapsed will turn it on in Tactical Strobe mode. Likewise if I have it on Moonlight mode and turn it Off, if I turn it On before 20 seconds have elapsed, it will turn on in the next mode (Low). On an Eneloop, it would only do this if I turned the Light Off, then On in under 3-4 seconds. If I waited longer than that, the light would turn on in the default setting (Turbo with head tightened, Moonlight with head loosened).
Aside from that little quirk, it's a great light on a 14500.
BTW, I also checked out the Nitecore TM11 (Tiny Monster 2000 lumen light) while I was at the store. Compared it to my Fenix TK41 (800-lumen version, not the newer 860-lumen). The TM11 is definitely a floody light. My TK41 would easily beat it as a thrower despite the TM11 putting out 2000 lumens to the TK41's 800 lumens.
