Really liked the K70 (it's no surprise, some call it the best keyboard in existence - dramatic, if you ask me), but due to reviews I've watched, it seems Corsair peripherals drivers suck, and might be annoying (if it is even a problem by now, I ask). So I searched for another option; the 710+ was the most pleasing (and everybody seems to have good experience with Logitech). Still, can't decide which one should I buy. So... guys? (Oh, and that "military grade aluminium" is worth something?)
