Valid question lol. I bought both with this new PC but couldn't decide which one I preferred so I ended up keeping both. Might sell the LG to a friend as I'm unhappy with the oversaturated reds and weird scan lines for ~30 minutes until the monitor warms up. It has less ghosting/blur than my Asus but I feel like the tradeoff is okay.
Talk about NVIDIA G-SYNC, a variable refresh rate (VRR) technology. G-SYNC eliminates stutters, tearing, and reduces input lag. List of G-SYNC Monitors.
