I had the Asus VG236H (it's the same as the HE but sold as a combo with the NVidia kit) and loved it. There were reports of screen bleed issues at the bezel edge, but I only had some very slight bleed when the whole monitor was displaying a black (blank) screen.
I'm sure the Alienware is also a good monitor, because it was the best monitor out before the Asus.
I'm assuming you have the glasses kit already?
Yes, I have the glasses but im puzzled as to which should i pick
