The Fenix is better in quality and overall output but the
WF-400/
WF-600 will kill it in the throw(and size) department(well, they aren't that much bigger, more of a sedan to wagon or minivan size increase). All three light have the Cree LED, the P3D-Rebel 100 has a Rebel 100 LED which is brighter(more efficient) then the Cree P4 used in the P3D-CE.
The P3D will run over 20 hours if you keep it in low(
runtimes, over 3 days on low), so will the P2D(
runtimes, over a day on low), the 1 AA Jetbeam CL-E(
review, also over a day on low) V2.0 will also run for over 20 hours on low. The Olight T20 will also run for a long time on low, similar to the P3D-CE. The WF-400/WF-600 light will probably hit between 15-20 hours on low with two batteries.
Cree, Seoul and Luxeon just make LEDs, they don't produce their own lights
