My instinct is they’re pretty much equal. Despite the LP having better glass capable of better correction in angular terms, a focal ratio of f/6 pretty much negates any advantage it may have had for lateral and longitudinal chromatic aberration.

Despite the availability of modern glass types, many refractor designs exploit this to achieve faster f/ratios or wider fields of view - but not image quality better than the basic ¼ wave criterion.

Provided you can accept a focal ratio of f/15 a humble 4” achromat can deliver superb high resolution images that would slay the fast LP.

So.. a draw is my guess.

If both had the same focal ratio ... now that would be a more interesting comparison.
