Weird, I have no complaints about my BD Storm, it's been completely reliable, whereas I've lost several tikka-type petzl torches to water ingress.
To the OP: if you're buying secondhand pay attention to the year of manufacture. LED technology has improved dramatically over the last few years to the point where older torches are significantly worse on brightness and battery life than current models.
My apologies guys! I meant I was looking for either of these two models, dont mind which.
The reviews for what ive seen on both seem pretty damn good and I dont really have much prior experience with either brand, bar fiddling about with those old Petzl bulb torches with the big battery pack
Thanks for the heads up about that though @pancakeandchips I would never have thought to consider that
