Increasingly I find it depending mostly on what the game was built for... I was raised, if you will, on PC point and shoots, and so my preference is for mouse and keyboard. But even a lot of AAA games these days that are console ports have noticeable pointer lag and aggressive reticule gravity or other aids. I find these really frustrating since they interfere with the 1:1 sense you get with motion on a mouse, so I'll switch to a controller instead.

Hogwarts Legacy is an example of a recent AAA release that has such heavy reticule gravity that sometimes the best strategy is to just hold an analog stick forward and not move it (e.g. in the broom races)... I hate this kind of thing but I feel like it's something you put up with as a PC gamer due to the popularity edge the consoles have. At least it tends to be games where fast aiming isn't a huge factor.

as a kid i played keyboard and mouse for all the games i played at the time (backyard sports franchise and other humongous games like freddi fish, putt putt etc.) then i moved to ps2 and then later 360 so now i am much more inclined to use a controller

i use controllers for RTS games on pc. one stick to scroll the map, other to select units. my wrists are too weak to use a mouse for several hours
