anyone Unfortunately I can't tell you that. However one of the the nice things about VA is being able to use a dark or black theme, which VA does very well, and another thing is that VA has good contrast even when you take the contrast control down after taking down the brightness.
Also, I've read good things about this TN unit: https://www.lg.com/us/monitors/lg-24MK400H-B-led-monitor
I was going to get one to see how it is because it's a cheap unit with excellent reviews and no one complaining about any eye strain. However, my Amazon site sold out of them after stocking them at a very attractive price level.
I believe the VA249 may be a bit better, but since I didn't get the LG to test, I don't really know. LG says the viewing angles are only
Viewing Angle 90º (R/L), 65º (U/D)
And the Asus is supposed to have 178º viewing angles, but I haven't read anyone complaining about the LG's viewing angles. Maybe that could be because people are easily pleased when they don't pay much? I don't know. TN used to have bad viewing angles, but people don't seem to complain about the current generation units.
In general, I recommend buying from a place like Amazon where you can try out the unit for 30 days before returning it if need be for a full refund. There's no substitute for using the monitor in your own home environment.
