Every time someone brings up a controller vs mouse and keyboard, most of if not all comments will push towards the OP to “switch to mouse and keyboard” because “it’s better!”
In my eyes, the person is already accustomed to controller, they’re used to the sensitivity, and if not it’s a quick change.
If they’re going to get used to mouse and keyboard they need to:
- 
find a reasonable mouse 
- 
find a reasonable mousepad for their situation 
- 
find out if they’re a wrist aimer or an arm aimer 
- 
make sure their windows mouse sensitivity is set to 6/11 for some reason otherwise everything else will be messed up 
- 
find their “optimal sensitivity” many of which tutorials are (subjectively) hard to find (the good ones) 
I’m both a controller and mouse and keyboard user but I find it easier to aim with a controller. It feels natural.
- “The control scheme that needs aim assist for fps games is good” - ??? 
- I’ve had this discussion a few times. It has always ended with me asking “do you have aim assist on?”. 
- Eh, you can’t get precision shooting with a controller in a fast-paced fight. 
- Had a console player join our Tarkov discord. Dude spent a week setting up his controller. Still got his add handed to him continuously until he switched to keyboard and mouse. - Using a controller without aim assist will never make you competitive against keyboard and mouse. Sorry, not sorry. 
- Deluded 
- Halo 1,2,3 Legendary speed run word record holders use comtrollers (yes, PC). I have not seen this with any other game. It is about how well a game is optimised for controllers. It is hard to land head shots with a controller in Counter Strike, but slightly easy in Battlefield (yes, without aim assist).
