The worst in my book is micro-HDMI. So many broken connectors, adapters, and cables... Even before USB-C became an option, mini-HDMI is just a different league of reliable without being that much bigger. A broken RJ-45 is still usable and fixable. A broken micro-HDMI makes you feel lucky it was the cable and not the device that goes in the bin this time. But only after hours wasted on fiddling with it because the closest shop carrying them wouldn't arrive until after the weekend.
