Question HDMI 2.0 vs DisplayPort 1.2

[Caplis]

I'm about to buy Dell Gaming S2719DGF, which is capable of 1440p and 155ghz.
It has two ways of input; HDMI 2.0 and DisplayPort 1.2.
I was wondering, which one should I use for casual, single-player gaming? The threads I found on this topic weren't quite specific.

DP is the best option:

2560 x 1440 at 155Hz (Overclock with DP)
2560 x 1440 at 144Hz (Native with HDMI 2/ DP)
2560 x 1440 at 60Hz (Native with HDMI1)

To be honest, it's your choice. There isn't much difference.
