I like your summary, but I think IQ here is a nebulous label. It seems to be based on resolution, but there's a lot more to IQ than absolute resolution, much of which he only touches on even in his full reviews. He rarely looks at backlit performance, distortion at varied focal length and focus distances, bokeh at varied lengths and distances. His testing tells us some about the resolution of a lens, some aspects of its CA performance, and some aspects of its distortion performance at an unspecified focus distance. While Sony and Sigma run neck and neck for resolution, with one lens weaker at some focal lengths and stronger at others, the CA correction on the Sigma isn't great. Sony and Tamron are very close in their correction. The Sony and Sigma had a distortion advantage, and appear to be about equal.
Anyway, I should note I'm not trying to belittle you or Frost. I like his videos, and I feel like he does a good job of introducing me to lenses I plan to rent. He's also one of the least pretentious vloggers and doesn't try to sell you on his personality, which I appreciate, but, like with anyone else out there giving you an overview with a single copy of a lens, you have to appreciate it for what it is, and it's usually a fraction of the whole story, especially with zooms.
