to 4/3rd chip when compared to 35mm lenses/5D. Tell me if I'm wrong

That's basically how I interpret the results of this comparison. Whether these results can be generalized to other lenses for the two systems is unknown. From what I recall, my wide angle EF-S lenses (I had 10-22 and my dad had 17-55 IS) showed some smearing in the extreme corners on the APS-C sensor Canon DSLRs. Certainly my present and past compact digital cameras (D-LUX 2, G7, GX100, F30, etc) tend/tended to show smearing in the extreme corners at wide angles. Thus, I don't think the relatively intact corners shown here for Four Thirds is a strength of smaller sensors in general, but rather a strength of the Four Thirds system (with the generous assumption that the results here can be generalized).
