I purchased this as my LG C2 was starting to get some burn in. The colors and vibrancy blew me away, I wasn't expecting it to be such an upgrade over the previous LG.
During my research I've heard the colors were oversaturated. But to me this is a positive. Also, the 144hz over the 120hz was definitely noticeable, mostly in the smoothness of the cursor on desktop. But please note this feature is only available when being used as a PC display.
