It depends on how big of a role precise movements play (that are controlled by mouse on KMB). And how much I gain from the analogueness of controllers. Take Death Stranding for example: Shooting is relatively few and far between and it rarely requires high precision when you shoot (most weapons are either splash damage grenade-types or fully-automatic with a generous enough amount of ammo). The trekking along to deliver packages feels much better on a controller. So DS is controller territory for me, even if it involves shooting.

Red Dead Redemption 2? Couldn't imagine playing it half as well with a controller, because most guns have a very low rate of fire, gunfights are a lot more lethal and (thanks to the "Scroll Wheel Movement Speed" mod) I am able to casually meander at different speeds even while getting all the benefits of playing with keyboard and mouse.
