Our Verdict
ASUS TUF VG27AQ
AOC CQ27G2
The ASUS TUF VG27AQ is much better than the AOC CQ27G2. The ASUS uses an IPS panel, which results in better viewing angles but worse contrast. The ASUS has better ergonomics, a higher peak brightness, and faster response times. Unfortunately, the ASUS supports HDR, but this doesn't add much. On the other hand, the AOC has much better contrast, so blacks look black in a dark room instead of gray.
