1-) I mean well noone knows what will happen with these monitors in 2-3 years of time. But monitors dont break easily. And since Auria is sold at microcenter and you are under warranty for a year I would say go for it.
2-) Response time is less but you wont really notice the difference much. I came from a 1080p 2ms gaming monitor and honestly I don't see a difference.
3-) Well if you can afford go with Asus, or Dell or HP but Auria will also make you very happy.
Just dont get a 1080p 2ms monitor for the price of Auria. Just dont do that. 1440p is awesome.
