Need advice for: asus xg248qsg or asus pg27aqwp or zowie xl2586+

Hello

I want to get advice, I already use G8 odyssey 4k 32 inch, but lately for few months I play much more competetive games than AAA, so I wanted to ask you a question, do u think that its worth it to get additional monitor just for competetive games?

I found 3 models and cant tell which one would make sense or I should just stay with my G8.

Thanks for help
