The USB flavors and so many others have a little plastic tongue on the female side which I think is the source of the alignment sensitivity and fragility issues. Lightning, headphone jacks, and RJ45 have a purely concave port which I much prefer.

edit: and if there has to be a weak point it should be on the cable side, not on the port side.

For USB-C, the weak point is on the cable side. For Lightning, it's on the device side (little golden contact springs). The lightning plug feels like it's made for eternity, I must say though.
