Honestly in speaking terms of performance. Make/model of 1080 doesn't really matter.
Only reason to pick a specific vendor is for it perks. Like Asus normally comes with 3 fans (though not proven to be more effective then MSI twin frozer setup). MSI comes with very basic lighting effects and decent OC out of factory, Stix normally has really good RGP lighting effect etc....
I personally picked MSI because of the nice overclocking out of factory which was tested by the manufacture before shipping. Ensures a very good stable overclock right off the bat.
