These are very similar to one another, they're both great choices. The LG one has better color accuracy since it uses a Nano IPS panel instead of the IPS Asus use, but it's not an immense difference, and won't matter at all if you're not doing colour critical work. The Asus one has 165hz refresh rate which is faster than the 144hz refresh rate LG has, however you won't actual notice a difference when you have the monitor next to one another. Everything else about either monitor is the same, they have the same contrast ratio and maximum brightness, and I wouldn't be surprised if you can overclock the LG panel to 165hz (I wouldn't suggest it).

AOC AGON AG322QC4
The AOC one does seem to be the best one, it is HDR400 certified, it's response time is 1ms faster, it has a higher typical brightness, (LG 250cd, AOC 300cd), and at last the AOC has an IPS panel which offers better colour accuracy and looks better than the VA panel the LG uses.
