I'd say we have the answer in the real life data, showing that MCTs have on the average better made optics.
Beyond any design differences, I am under no illusion observing conditions play a huge role in how much we appreciate our instrument (any instrument). No doubt observing conditions greatly influences how we feel about the design we have. The MCT has stood up amazingly well, as surely any descent scope would.
We really get to see what it can do in real world lab-like conditions with variables controlled or otherwise favorable, cooled to ambient, collimated, clean, and with calm and clear air above. If you want to push the scope to the limits of it's theoretical and real world performance (which actually appear to be very similar), this is the time and place to do it. In the tropics, we experience almost nightly those excellent nights others crow about when their own scopes preformed at their best - those nights when their jaw dropped. My current MCT drops my jaw almost nightly.
Those are the nights when you can take the time to observe any differences in the end product design and production. The MCT may be better than another design in one way or another, or it may not. One might imagine it would be more difficult to observe differences in 2" arc seeing except during the fleeting best moments. We need to get both mass produced samples into a lab or in lab-like conditions to really appreciate soft contrast or high resolution capabilities of each.
However, if ray tracing and theory can be approximated in real world observing, then maybe speculation on production, star testing, and understanding each design can tell us what to expect. All that remains is to observe it. I dunno, I have become a believer in theory (having kind of seen it in action) observing planets, lunar, and double stars under lab like conditions. When the atmosphere allows a clear split on an otherwise more difficult Dawes double or high contrast extended object resolution down to about Lambda/D, something good is happening.
Maybe that something good is an appreciation or inspired love of the design that accomplished such a feat. Nothing changes the fact the design put up that jaw dropping image when observing conditions allowed it to.
