Depends if you are bothered about weight and what you want if for. Nitecore NU25 with shock cord strap mod 33g (on my scales) Fenix HL60R 97g. My NU25 is faultless, reliable, good beam for walking and running and I can't imaging how I would break the bracket. I was a bit concerned about how well the 2mm shock cord would do with my head bobbing running and walking fast but it works absolutely fine with zero bounce, I guess because the lamp is so light. The way it charges with red/green LED to tell you what is going on is excellent.
My wife put hers in the washing machine, in her race vest, and it came out working fine and in perfect condition.
