There's not a whole lot of reviews yet.
BenQ is weird, no FreeSync, no G-Sync, no Lightboost. Pretty poor at that price.
No idea about the Acer.
Generally all of them have worse colours than 120/144/165/180Hz monitors.
Highest overshoots = worst colours, but lowest response time on the AOC. Your only option with FreeSync though.
Asus a bit less overshoots, a bit better colours, but higher response time. G-Sync.
