I can't personally speak to the quality of either the Asus or the Acer monitors as I haven't personally used either of them. As far as Asus support, I have used many Asus products (mostly motherboards) over the years and have never had an issue with their technical support. I have even many times called them on legacy Asus products that were way out of their warranty coverage and always received welcoming support from them and wasn't just brushed off as if it was not relevant. I would have to say strictly from a product quality point of view, Acer has just stepped into the gaming market recently compared to Asus who has been making gaming quality products for a long time. I have not yet had a personal bad experience with any Asus product. I have however had a number of issues with Acer products (mostly laptops of non-gaming style). I do like the fit and finish of the Acer better however for this kind of money, even with a drop I will have to side with Asus. Just my $0.02.
