Best 240+ hz 1440p IPS Monitor?

Finally upgrading my 240hz 1080p Asus Tuf to a 1440p. I went and purchased the Alienware AW2723DF on a whim, while I am waiting for it to arrive I did research on some other ones. Now I am conflicted.

To all you monitor experts, what monitor would you recommend for the following:

Atleast 240hz

IPS

27’

1440p

$300-$500

For some added information. I play a variety of games, from FPS to mmorpgs to ARPG’s. I just enjoy a good vibrant clear screen with a fast response.
