The MSI Optix G27C4 and the ASUS TUF VG27VQ are both 27 inch 1080p VA monitors and perform very similarly. The MSI has a much better response time, so motion is clearer, and both the gray uniformity and black uniformity are better on it as well. However, the ASUS has a much better out-of-box color accuracy and the stand allows for more adjustments. The difference between the two really comes down to personal preference and how you'll be using it.
