Okay, now it's clear that you're full of it. Switching to MnK after using a controller all your life isn't an easy transition. Using a mouse doesn't mean you just get to click on heads either. You have to track enemies in a 3d environment, not click a box on a spreadsheet.
You say that you can use both, but have to go back to check mouse out again? Moving it around for a second in the game isn't the same as playing. A mouse may feel more intuitive and better to use, but there's no assist. Every controller player I see posting a video have no problem moving around nearly as fast as MnK user, and then have the added benefit of the game essentially aiming for them. Once they see a player, they're literally locking onto them. No sway, no jittering, just locked on with their laser gun.
If you can't feel the aim assist in 2042, then I don't know what to tell you. It's strong. COD might be more so, I don't play it, but 2042 has some of the strongest assist out there.
Comeback to us after you turn AA for week and see how well you can do without it. Hint, it's doing most of the work for you.
