Sigma's famous statement: it wasn't looking to surpass Nikon and Canon, but rather the Zeiss Otus 55mm f/1.4 has a way to go judging by the graph in the review. I would have expected the FF graph to look like the 7D graph based on this bragging. The Otus' whole thing is sharp corners at f1.4. That's expensive to achieve.
You don't seem to know how to read the graph or what a typical graph is. This lens actually has LESS falloff in resolution between the center and corners than the Zeiss Otus, and 3 times less falloff in corner resolution than a typical competitor.
SLRGear hasn't reviewed the Otus, your statements are baseless.
SLRGear brought up the Zeiss in their own comments.
