Do you trust this one anecdotal experience more than lensrentals' controlled test of 5 copies of the same lens, which showed it to be as sharp at F2 as the 35L at F2?

If you trust that test, you also believe that the old 35/2 is slightly sharper than the 35L, both at f/2. Roger is a funny guy, in its own way.

That's not what that test says. The average MTF of the 35L at F2 is higher than the average MTF of the old 35/2 at F2. The center MTF of the 35/2 is 835 compared with 830 for the 35L at F2. That difference is well within statistical margins of error, so it doesn't claim that the 35/2 is sharper. Many users claim that the 35/2 is sharp in the center wide open. It doesn't seem crazy that it would be approximately as sharp as the 35L in the center. The 35/2 really falls off at the corners.
