Brief backstory, I've tried (and own) some pretty expensive picks like Red Bear, Purple Plectrums, V-Picks, Gravity etc. Which are all great, but I've gone full circle and realised good old Dunlop is no slouch, and obviously much cheaper and more accessible.
Shortly summarised, these picks just feel and sound right to me. I also ordered a set of Ultex and Max Grip of the same gauge, but the Gators feel thicker and flex less for some reason - the Max Grip in particular is quite flexible for a 1.14mm pick. The Gators and Flow (both 1.14mm) share the #1 spot for me, where the former excel for rhythm and the latter for lead. Not that you can't use either for both, of course.
Even though the white powdery substance wears off with time it still has a better grip than something like a standard Tortex, due to the rougher surface. But I haven't used it in a hot and sweaty gigging environment yet.
Picks are so cheap I would recommend trying as many as you can, the variety packs are great as different picks can vary in stiffness (which, at least for me, matter more than the actual thickness).
