I have been using my ACER XV34OCK 34inch 1440p @ 144hz (non-curved) for about 1.5 months and the motion clarity is superior to my MG279Qs which are 144hz IPS panels. It makes sense that newer panels surpass older ones but @ $379 on discount from Microcenter and $550 when sold regularly, I don't see why anyone is purchasing the overpriced LG and Alienware options. Regardless, enjoy your new baby.
