It's mostly going to be used for gaming I might buy this monitor a little later (lets hope the price is the same!) but do you know reliable brand names? Or just links to lower or around the same price range?
Gaming.
Cool, then you'd probably make use of low response times, high refresh rates, and wouldn't care much about color accuracy or viewing angles. So you'd be looking for a TN (Twisted Nematic) panel. Those are the cheapest for this kind of specific requirements. (Also most common.)
Yes, the ASUS ROG swift is probably the most elite option available at this time. You can determine if it fits your budget or not.
As for brands of monitors, here's a general summary: (Just to give you an idea.)
Gaming brands
ASUS, Acer, AOC, BenQ
Business brands (General use and light gaming)
LG, Samsung, HP, Dell, Philips
Professional (Non gaming. Work specific screens)
NEC, DoubleSight, HP, Dell
Cheapest (Beware of low quality)
Monoprice, Acer, AOC, Philips, ViewSonic, QNIX, Crossover, and lots more
There's most likely other brands that I missed, but this just to give you an idea of the brands out there. Each company, like HP for example, has its low end, and high end models. You can visit their websites and browse through them there, or use a website like Newegg.com to filter for specific features, like 1ms / 120hz etc.
