The Gigabyte G27QC is slightly better than the ASUS TUF Gaming VG27WQ1B. The Gigabyte gets brighter, has a quicker response time at its max refresh rate and 60Hz, a lower input lag, and better ergonomics. However, the ASUS displays a wider SDR and HDR color gamut and has better out-of-the-box color accuracy, but this may vary between units.
