If the OP is just talking about output then I would say the Fenix offerings right now, or the Dmini for throw.
If they just want the best all around 1x123 light then I still submit the EDC series is far and away the best I have seen for quality, robustness, quality and quantity of light, UI, light levels, tech etc. A 60 lumen HDS EDC ain't that much dimmer then a "135" lumen Fenix to the eye. I have an love my Fenix products but I personally think the current HDS EDCs and upcoming Novatac EDCs will be where the bar is set.
Once again, this is no dig on Fenix as I think they put out a fine product for the money it is just that my interpretation of the best is the above.
