Pretty much every pro uses one of the top 2 choices there, but it's pretty expensive and TN. Note that this might just be because of brand loyalty and sponsorships. The alienware is good especially for the price but it seems it is weaker as an overall monitor other than just gaming.
If you're ok with 27in, these two should also be good.
