Well Displayport is a weaker signal on the backend (GPU side) than HDMI and requires a SST/MST scaler to amplify the signal again on the monitor end. So as a result you need a thicker cable for the same signal on Displayport than HDMI. A 28awg HDMI cable can handle 4K60@ 4:4:4 no problems on a standard HDMI 1.3/1.4 cable at runs up to 20 feet, but good luck doing that on a DP cable. You need at least 24 awg cable to pull it off on DP.
The other issue is supply and demand. Large supply and demand of HDMI products, so the problems have been mostly cleared out, and HDMI cables are pretty standardized, and even thick 24awg HDMI cables are selling for like $10-15. DP cables are all over the place, some of them still sell with live 20 pins which can damage your hardware and has less available bandwidth than cables without the live 20 pins, also a 24awg DP cable is currently going for like $110+ taxes and shipping.
