Xbox controller or keyboard mouse better on FPS games?

[袭禁评]

I've always been confused why Euro gamers and American gamers use Xbox controller to play all types of games, and we always use typical keybord and mouse, what my problem is, when playing FPS game i'm using xbox controller to scroll the pespective, the pespective rotate uncomfortably even makes me sick, while mouse makes it naturally to rotate.
And how to use xbox controller to aim and turn around? I'm not really like playing FPS by controoler

Depends on what you're comfy with, but KB/M tends to be better for FPS games.
For some other games a controller is better though

For quick aiming and reflex shots nothing beats keyboard mouse when playing FPS imo. When I go round to my friends house and play on his PS4 i find the controler cumberson when I play BF5 or PUBG, but each to their own.

Mouse is better for FPS. Reasons why

On pad you're restricted to maximum of 2 speeds when aiming. Slower or fast/normal. Changing sensitivty setting still leaves you with 2 speeds.

Mouse you can be as slow or as fast as you want or need. mouse games use a softlock/auto aim for consoles fps to help controller use.

Other aiming disadvantage taking your thumb of the thumbstick to press one of 4 buttons means you can't aim and look around. On Mouse you can still aim while clicking other mouse buttons or keyboard buttons.

Same applies for left stick. On a controller you stop moving when you want to use the other 4 buttons near your thumb.

Thre are other reasons but those are the main onesfor me. Why I never play fps or third person shooters on consoles......least not the online components.
