Our Verdict
AOC AGON AG271QX
ASUS ROG Swift PG279QZ
The ASUS PG279QZ is better than the AOC AGON AG271QX for most people. The ASUS is an IPS monitor with much better viewing angles whereas the AOC has a TN panel with almost instantaneous response time and better black uniformity. The ASUS PG279QZ has better ergonomics and a BFI option to make the image crisper.
