Should I buy the BenQ XL2411T 144hz Monitor or Astro A50's

Hi, currently I can only get one of these. My monitor I'm using is actually a 32" 60hz TV and I think it's to big for the range I'm sitting at. However, the sound and mic I'm using isn't so good either.

So can anyone suggest wether I get the BenQ XL2411T 144hz Gaming monitor or the Astro A50's

And yes, I have a good gpu to handle 100 FPS+

Thanks
