alt Hacker NewsUSB-C is better than A in that it works in two orientations instead of one, but the correct answer for connectors should be any orientation — the best connectors are cylindrical connectors: barrel plugs, RCA, BNC, banana, phono, TRS, TRRS, etc. Just make them round.
Man, there’s nothing more satisfying than the feel of a quarter-inch TRS plug slotting in to a high quality jack. Truly one of the great plug designs.
