Klauss' optical quality scores are based entirely on various aspects of lens designs.
In real use, distortion, chromatic aberration and vignetting are most EASILY corrected in post-processing, so the only criteria worth considering are resolution, flare and bokeh. Since the latter two aspects are not presented, the only aspect left is resolution. If you miss out the details, you can never recover them.
Now, look at 18, 24-28 mm and 55 mm. Examine performance at border/extreme relative to the center. Take off your fanboyz glasses and stare at the optical results.

Note that the Sony has a center resolution that might exceed that of the sensor, even wide open, at wider lenghts, whereas the Canon only barely makes it into excellent in the center. But the Sony is a step behind in the borders. Different, but can't say that one is simply superior to the other.
The CA is pretty hefty on the Sony, so much so that I wonder how much it can be corrected. It would be interesting to see an analysis of this, somehow.
Note: I am not a Sony fanboy. Indeed, I avoid them like the plague for always using non-standard interfaces.
