I think you are painting with the same broad brush you accuse me of. I am not for folders to the exclusion of everything else. And I will have to admit I haven't done side by side tests. If you have compared many folders against TLR and found the TLRs outdo any folders, good for you.
I have only shot 4 TRL; Yashica MAT 124 G, Rolleiflex (with Schneider-Kruesnaught f/3.5 lens), Welta Reflekta, and Welta Perfekta. I loved the Yashica, found the Reflekta OK, and kind of liked the Perfekta. I could never find any love for the Rolleiflex. I have used several folders and liked them all (except the poor working Mosdva). But that is just me. And as I said, I haven't done side by side tests, so the fact that I liked them and thought they gave me good photos is my evaluation only. All my folders except the Moskva clicked into place well. Perfect? Well, I don't carry a square with me, but my eyes are still pretty good.
I am glad you are happy with your TLR. As I said, I really loved my Yashica and took a lot of photos with it, so I understand how some people really love them.
I did not accuse you of anything. I said that there are important
design deficiencies in the folders that make them inferior optically
to TLRs. (And to most other cameras.) This is not my opinion. It
has nothing to do with you. It is a fact of their design, both in the
camera body and (for most folders) in the way the lenses focus.
I also said that optics are but one consideration, abeit one the OP
seemed to care about. As Ernst said, how the shooter is printing
and presenting the photos make a big difference in whether the
optics matter. For my own purposes, I welcome optical irregularity.
I will never own a Summilux; a Summar is my lens. Because in the
brave new world of digital imaging, perfect fidelity of optical resolution
is BORING. (That one was an opinion, by the way.)
It doesn't take anything away from folders to recognize their limits.
To repay your condescension: I'm glad you enjoy yours. I enjoy
mine too.
