My recommendation would be to go with a controller. It’s pretty relaxing and you don’t use wrists, like with kb&m. It’s more thumb and forefinger action.
But…it plays a bit differently and pathing can be an issue.
There are a number of “lazy builds” that use few keybindings which are good for this. You can also use a lot of bindings if you were into that sort of controller play via menu swaps.
Any build, really. But fine control of skills not directly highlighting an enemy is tricky. Kiting is very different = you need to turn and move in that direction, then turn again. And you need to be micromanage your path as GD has specific walkable areas ( the kb+m AI automatically calculates an unblocked path).
You visually have full immersion in the beautifully-designed GD world when you can rotate the camera with such fluidity. But it has some gameplay drawbacks.
Also, the latest QoL improvements in component management and item pickup have made controller life easier.
