My biggest problem with those was that mini didn't have a strong enough friction fit and would become loose easily, and micro would wear down and break so easily. Luckily it seems that USB C has all the right qualities. It's symmetrical but reversible, it's durable, it clicks into place well, and it's form works well on desktop, laptop, and mobile equally.
So micro and mini usb are superior!
Mini is fine. Micro is very close to being symmetrical that it might as well be. For cables that small, reversible is the way to go.
