Yes, I like my CR123 lights because I use lithium primaries, and I don't need to worry of damaging the batteries. Some of my AA-lights I prefer alkalines because of the same reason. But I use to regularly control that the cells have not started to leak.
Ok, so single AA-lights will not be damaged by cell reversal? I have several lights tailstanding for making a cosy atmosphere at home as a complement to candle lights. Quark Mini AA, CR2 and CR123. Also Quark Preon AAA, Nitecore D10, 4Sevens regular 123 and Fenix LD10 I sometimes use for this purpose at the lowest mode. At this mode these lights run for days and nights and therefore I use alkalines to avoid overdischarge the batteries.
