First person shooter or third person game where aim is important, has to be keyboard and mouse. Pretty much anything involvong driving a vehicle, gamepad is better. In games like GTA I often use both, switching as necessary. Mostly I play FPS games though so KB+M is my most used input method. Some console-focused FPS games such as Halo I'll play on controller if it's all that is available, such as with the Steam Deck.
