I'm not an expert, but some searching shows its an IPS panelhttps://www.asus.com/Monitors_Projectors/PB238Q/#specifications
I'd pick the PB238Q it has an adjustable stand and the base looks much more stable.
Thanks for your opinion!
I'd want to know what kind of IPS panel PB238Q is, tho...
Cuz I heard that E-IPS is 6-bit panel like TN, so less colorful...
On the other hand, P-IPS is much more colorful IPS panel.
