Sugino claims that Sugino 75 crank arms use a proprietary "SG75" taper, which is complete nonsense.
You can argue about it on Reddit until you're foaming at the mouth but we've measured Sugino 75 bottom bracket spindles and compared them to many other ISO/Campy spindles, and are 100% confident in saying Sugino 75 components are ISO taper.
