Games like Palworld and GTA are better with a controller. Games like Cities: Skylines and any game requiring significant precision are better with a mouse and keyboard.
I prefer over the shoulder games like GTA with keyboard mouse and controller.
Controller for general navigation and when a firefight starts to go down, my right hand switches to the mouse and my left hand is still on the controller, resting on the desk. When the firefight starts getting hectic the controller gets dropped and it’s WASD from there on out.
I don't think it's easier, since many of the ranged weapons in that game require good aim, which is better with a mouse, but I do think it's more fun with a controller.
