Counted from tracked players who own exactly one of the pair: they chose it, and every battle they played on this brawler was played with it. Both sides are equally invested in the brawler, so the gap between the two win rates is the ability rather than the player — read them against each other rather than as absolutes.

Gears owners buy

Gears cost coins and you can only run two, so what owners have bought is a real preference.
