Honestly each of the setups work well with different characters, I was messing about with them last night testing them out more...
Hoodlums Linear CURVE 1 + Settings work well with Soldier, Zarya, Tracer, but it's a garbage set up for Widowmaker and Hanzo...
The Expo set up works better if you want quick turns or characters where you don't need to "aim", characters such as Winston, Genji, Tracer, Symetra, Mercy, Junkrat..
Then the OP Linear/Curve set up seems to work better with Widowmaker, Hanzo, McCree.
I've been using Hoodlums set up for Soldier & Zarya and it feels brilliant, I absolutely tear it up with Soldier, I was good with him before I started using Hoodlums set up but now I am even better.. but for other characters it's not the best. The thing I like best about Hoodlums set up is it's excellent for tracking and the crosshair doesn't stick to the body so it doesn't tug away from the crit boxes when you're trying to get the crosshair there... whereas the linear one I feel really drags to the body more, it's good tracking, but harder to drag the crosshair to the head.
