When your life depends on them, I'd go with Surefire. I have total confidence in their weapon lights (my X300/Ultras have had no issues on several handgun/rifles) and if I were a cop that's definitely what I'd use.
For my EDC/other light obsession, they just don't offer the size/output/battery/price options like others. In that case I really like Fenix and have had great luck with them. Zero issues with their lights over the last 6-8years, and have EDC'd a PD20/PD22UE the last several.
I have had two different Fenixes fail on me. Granted it was in 2007 or such but I still don't want to experiment with them anymore. It was the first generation of L2D I think. They have multiple modes as you know. Well one went into a single, weird morse-code like mode, flashing randomly. I exchanged it for another. It also failed. I got a replacement and sold it NIB. Sadly, an incan Surefire 6P would be more reliable than that as old as it is. I will admit that at the time, the L2D was an impressively massive lumen output and very high on the "wow" factor. I got the "wow" factor every time I ran it. 200 lumens out of 2xAA was, and still is a big deal out of a 2xAA light. The 2x123 was even more impressive. I am not sure if any Surefire lights generated the "wow" factor back in 2007. But today?
I've had zero failures with Malkoffs however. If you never want a failure, get a single mode light with a bulletproof module and a twisty tailcap. You just eliminated all possible failures. It just works and works.
