After using a few different 32" VA 1440p monitors I'd come to the same conclusion too. Though smearing and lag was much better on the LG 32GK850F, compared to the AOC AGON.
But once I sat down and used the monitor, every now and then I was noticing the pixels that make up the fonts on screen. It was kind of jarring, would move my eyes as looking at text on screen and suddenly notice pixels.
I've looked into 32" 4K monitors, but they are all VA unless you spend £600+
The VA panels need to be sat over three feet from them else you'll notice gamma shifts at both sides. I have read too many complaints of this issue for it to be just nit picking.
I really wanted 32" but I'll probably end up sticking with 27" 1440p unless an IPS 32" 4K turns up at a reasonable price...or get the Acer 35" ultrawide VA...or the Dell TN...choices!
