I know this is an old thread, but I had the similar issues trying to decide between 16-70 vs the 18-135mm, and I ended up buying both with the intention of selling the subpar lens after running through number of tests.

Both lenses I got had no apparent softness in one side of the image, an I also ran a simple decentering test and that didn't point anything obvious. So I assume my lenses are within the QC standards.

I did some lens chart tests and I documented findings in a blog article as the number of tests alone wouldn't be possible to write up as a single post in here.

Thank you for the effort and thorough test.  I'm  glad that the 18-135mm held up well in my most common usage (outdoor f8 travel pictures).
