I think I'd give the edge to the Dell if you can get it for a similar price. Its 165hz mode is native, not OC'd, and has DP 1.4, plus some USB ports. The USB ports are convenient for me, though I only need 1 or 2.
The annoying thing about both monitors is that the controls are on the back instead of the bottom or front. This makes it hard to turn the monitor on if you have a multi monitor setup. The only way to reach to it is underneath and blindly.
It's not too difficult to get to if you can reach into it from the right side, but if you have another monitor to the right of it up against this one, the only way is from the bottom.
