I'll second the recommendation for the Spa cranks. I have both those and genuine Sugino cranks, and they're the same forging. See https://groups.google.com/g/internet-bob/c/yNE7e5iy6fg/m/M45KJfMEAQAJ, where I included some comparison photos of the two.
The Stronglight Impact cranks are another badge-engineered crank actually made by Sugino.
