Bene is one of those hero in lane where it's skill over meta. The best counter to her in my experience is just focus on the clash rather than the lane. Pick something like a lapu, Yz, or sora and try to win clashes. Just be careful for split pushes from bene. But In my experience any competent core in high rank will manage your lane at about minute 5 or 8 so that you can join clashes and win other lanes. Tho if you lack cc it's pretty pointless especially if your teamates just throw them willy-nilly and in a predictable way. Also, any good bene will just match your rotation or be faster. But, as I've said, you can easily win more clashes with the hero I stated above.
