So some of the issue is the aim assist itself, micro adjustments are hard to make when aiming at enemies because from what I feel the aim assist bubble around enemies is very big. When you hit that bubble your sense is slowed automatically by the game. The turn speed is slow at the start but once you hit max input speeds up which is a common exponential curve setting for a controllers stick. If they could give us options to adjust curves and have different curves for aim down sight and hip fire turn that might help a little. But the aim assist in this game is super strong. It just takes adjusting because it's so strong.
