I'm having a hard time deciding between this monitor or the BenQ XL2730Z.
The reason is this only has a Freesync range of 35Hz to 90Hz where as the BenQ has 40Hz to 144Hz.
Just think if you are going to use sometimes FreeSync or always. I play CS:GO for example with Freesync off because I think is better play like this way (more FPS) and I'm enjoying the Asus MG279Q for the real colors that brings me the IPS panel.
I had the same hard time, but I always wanted to have an IPS screen hehe maybe the Benq have some features for help gamers, but I'm the class of people that setup his screen one time and don't touch the setup if don't need to. If you are like me choose Asus, I you like the extra feautures of Benq and you like to put a setup for movies, other for games, other for... choose Benq, because it has a controller with better access for do that things. And for I said before of FreeSync ofc
