Personally, my favorite is the gyro on button hold, bound to the aiming button, as Breath of the Wild originally did. I’m personally peeved about the always-on implementation on Splatoon though, because any slight tremor in your hand means your aim will suffer. (At least they had the decency of adding a dedicated recenter button.) And how do you go three games in a row not allowing the players to correct the vertical aim with the stick? What in the world is the rationale for that?
Gyro always on, flick stick, capacitive thumb to disable (if my thumb is on the stick, I’m either ratcheting or flicking)
