I have the SF30 Pro since a few years now and there might have been different revisions, but I definitely did not observe that. And I played through Hollow Knight with it, so I doubt that the controls are imprecise - I would not have had succeeded. Granted though, neither tried Tetris nor a classical fighting game.
But it has a huge problem of false diagonals, making is absolutely worthless to play tetris, or any fighting game that requires precise control. If you need precise controls, avoid this model.
