It depends on what it looks like in real life and whether using it in a dark room is important to you. I've bought three of these recently and another I returned. In normal use they are great, no pixel defects and excellent colours even before calibration. However they all have the slightly yellow bleed bottom left and white bleed bottom right, but not that much worse than the U2410s I replaced. This is only visible in the dark or near dark though once the brightness is reduced from the excessive default. It's tricky with the bleed and IPS glow as the larger the screen the more apparent that becomes as well.
I considered the Asus PB278Q but wasn't sure if PWM would be a problem as well as the Viewsonic VP2770 but decided the huge stands would look horrible with three next to each other (and didn't fancy the extra cost of changing them).
Given I change monitors every few years I figure the U2713HM is great value and there is some compromise to accept, unless you wish to go through numerous swap outs.
