I can feel AA when sniping on NEXUS whereas I can't feel it at all on APEX. The caveat being AA is much stronger in PvE than PvP, but it's also stronger on NEXUS than a regular controller due to the high degree of reticle control with motion aim.
I find sniping in general to be easier with NEXUS as I tend to jerk the mouse on APEX and overshoot my target. And I very much suck at using a regular controller, so that's saying something about how much of a crutch NEXUS is in my hands

Check my VODs on Twitch (link in sig) if you want to see some NEXUS action in Destiny 2. I'll be streaming again this week and D2 is my go-to game.
