I have no idea, but I think we are safe to assume that both lenses are good enough for any purpose. Was there really much progress regarding lens resolution in the past 50 years - I doubt it. And Rollei had quite stringent quality targets, in the old days, that the lens makers struggled to meet...
Regarding coating, even the oldest Rolleiflex Distagon was coated (single coated...).
The Schneider Super Angulon now called the w-apogon is also a very high quality lens. Regarding the HFT coating I have found that it does make a significant difference with the 80mm Planar.
