Hello
if you are using nVidia GPU, I would go with AOC AGON AG273QCG for G-sync.
BUT
VA panels on those other two will look better than the one above. Otherwise they are very similar and you wont feel difference.
Basicly it allows nVidia to use it. So yes.
I have Samsung display with 144hz and without G-Sync or Freesync and with VA panel it looks very good...I would go with that
