Thank you.

Lucky would be the one who could make a direct comparison
If we look at the cost, recent limited edition of CFF132mm was priced nearly 2000 USD less than AP130GTX. The AP has a larger claimed imaging circle (65mm vs 55mm), so that's one difference in optical performance. CFF is being hand aspherised, not sure if AP is still doing that and whether that's needed for GTX. As for polychromatic Strehl - no idea. Maybe except CFF's 105mm f/10 - apparently Strehl above 0.99 in the entire visible spectrum. No doubt AP delivers scopes as close to perfection as humanly possible within their parameters (f ratio, aperture etc).
