I suppose one could dispute "in active use", but D-sub connectors predate DIN connectors and are still in use today. I see them primarily on industrial equipment and, obviously, not on PCs much anymore. Given that MIDI is pretty specialized, too, I'd say that D-sub is at least as common, if not more so.
