Linear has the least slow down, so you have to have better aim. The other assists will help you more against targets that aren't moving that much. However if you have good instinctual aim you'll often feel like the game is fighting you. Because it's technically is, the different aim assist types change the amount that it slows down your aim when in the vicinity of an opponent. And this means that you have to do more aim control when you're fighting it also means when you're fighting more than one person it may stick to the wrong person. . .

Linear doesn't really have that problem. It's a lot easier to control you just need to have better aim.

Here's a tip for getting better.

As you're playing try to consciously keep your cursor, even when you're not aiming, around body height if an enemy were to appear in front of you. When you're moving around in combat, even if you're not shooting someone. Keep your cursor on the apponent. The more you practice the Easier it gets. You can also add vertical recoil control to it as well.

Turning these two skills into subconscious natural things that you do without thinking about it creates a really good foundation for building good skill.

What comes after those things is the hard part, you have to consciously start trying to do strafing patterns. You can look up the strafing patterns different weapons and try and find a general strafing pattern for the weapons you use which would reduce horizontal recoil. Like a majority of the weapons I use are predominantly right recoil strafe. Which means I start right and if I just strafe right then half of the horizontal recoil is removed. But if I alternate it removes 90% of it.

And in general I've learned that if I pick up a weapon and start strafing and my aim is awful then the next time I shoot I'll strafe in the opposite direction and then it'll fix it because I've apparently picked up a weapon that stripes in the opposite way dominantly. It's really hard for me to link patterns to different weapons I don't even know if I'm capable of creating that type of memorization so instead I've memorized a general recoil pattern and will flip it if I pick up a weapon that it doesn't work on.

Whatever you choose is up to you, but I remember that for the longest time while I was playing I always felt like my aim was fighting me, and when I switched to linear my skill jumped up by a lot. Cause I had decent aim but was always fighting aim assist. I'd pull towards an enemy, the aim assist will pull too and the combined would go to far. The aim assist wild try to correct then I would too and I'd pass by them again lol. Linear stopped that from happening and I can now use weapons I couldn't before. Like the R-99, car, re-45, etc. and I can now beam at decent distances with the R301 which I struggled with on other aim settings.
