New monitor: MA270U vs PD2706U

MA270U vs PD2706U

I'm looking for a monitor for my Mac(s) and was looking hard at the new Asus 5k option, but would really like to not spend that much so I figured I'd give a 4k option a go knowing that even though it won't be as sharp as a 5k option it will be a significant step up from my current LG 32" 1440p monitor and I am unhappy with the text crispness of my current monitor.
I was looking at ordering a MA270U, but I see the PD2706U is now on Benq's holiday sale meaning they are both the same price. Which monitor is better?
