Our Verdict
AOC CU34G2X
ASUS TUF Gaming VG34VQL1B
The ASUS TUF Gaming VG34VQL1B is a bit better gaming monitor than the AOC CU34G2X. The ASUS has significantly faster response times, but there's noticeable black smear on either due to their VA panels. The ASUS has a 165Hz panel compared to 144Hz on the AOC, and it also gets significantly brighter and has better reflection handling, so it's a better choice for well-lit rooms. However, the AOC has better ergonomics because it has a much wider swivel and tilt range.
