I said in order to get best performance, a lens MUST designed and optimized on that specific crop format.

That is actually not true as a well designed/optimized FF lens may also be outstanding on APS-C as well. On does not necessarily preclude the other. Many cases of that.

Still try if there is a well designed APS-C lens and optimized on APS-C sensor will still beat that FF lens on the same APS-C sensor.

Not really the case...In general. Too many really good FF lens out there (and expensive ones) so you can almost always find a FF lens (at a given focal length) that will out perform a dedicated APS-C lens (at a given focal length) across the frame.

Canon and Nikon APS-C/DX formats are not really are good examples as Canon and Nikon don't put much resources on their APS-C formats but in their FF formats. I have no doubt provided Canon and Nikon seriously designed and optimized APS-C lenses and don't mind to sell as high as their FF counterparts by using the same quality materials, such APS-C lenses will beat FF counterpart lenses on APS-C cameras.

One of reasons they don't do that APS-C shooters unlike FF photog in general are unwilling to spend premium cost on such pro-graded lenses, and still turn out not as good as FF counterpart lenses on FF cameras. Just imagine how much cost will be if Canon or Nikon ever designed a zoom as good as or even better than Sigma 18-35/1.8 (that already beats EF 24-70L II on APS-C although not covers the same AOV)? How many APS-C shooters will buy such super-expensive premium APS-C lenses? It is not worth as they will rather move to FF with similar costed FF lens and still performs better on FF.

The problem is that most outstanding EF lenses that designed and optimized on FF sensors have no APS-C counterparts that cover the same or close FL.

True, that is a problem...and mostly a result of a business choice.

Unlike APS-C platform that Canon and Nikon don't commit all resources in and not the only choice in their lineup, Panasonic and Olympus commit 100% of their resources into this mFT platform and design and optimize with the best effort on mFT lenses that work better than lenses designed for larger-format and used thru adapters.
