I'm no longer a fan of primaries... they don't stay full charge for long and I don't like using them when they're partially run down. Don't like using them up and discarding them one after another either. But I do keep a supply of CR123 primaries (and L91, L92 lithium primaries) in sealed containers in the fridge for back-up/emergency use only.
These days, its rechargeable li-ions all the way for me, with 14500, 10440, and 18650 as my preferred sizes/formats. Since I got into single AA-size lights, my lights in the 16340 format aren't getting much use anymore and when I do it's with rechargeable 16340 li-ion.
Even in my AA lights, I run with rechargeable li-ion except for brief & only occasional use of Eneloop AAs while a li-ion is recharging. The only light I have now that requires CR123 (won't run on a rechargeable RCR123) is my E1B, which has been relegated to shelf queen mostly these days, in favor of the new multi-level/multi-mode AA-size lights.
I think a good AA size light (D10, Quark AA, Jet I Pro IBS v3) that can run on 14500 li-ion (and all the other AA size cel types, if need be) is truly THE sweet-spot/hot ticket in compact size lights today! Reason? 14500 matches 16430 output and beats it in runtime... plus lights that run on 14500 can be powered by L91 lithium, AA Eneloop, and the lowly alkaline. CR123 lights don't have that powering versatility.
