yes, what's happening is that I'm conflating lateral (edge) CA and longitudinal (center) CA. The 8x42 SF's are outstanding at CA except for the periphery of the field. And the 8x32 is better than the 8x42 in that regard.SF 8x42 is especially famouse for high CA on the edge of the fov.
if you consider CA only in the edge, EDG has much less CA then SF. but at the center of the view, EDG has bit more CA then 8(8.5)x42 SF, EL, NL.
those 3 bino has very large gap of CA between edge and center.
what I mean is, if you number binocular's total CA '10' there are some bino that have '2' on center and '8' in the edge and other bino that have '4' on center and '6' in the edge.
SF is former, EDG is latter.
In my head I don't see the same hierarchy as most, with one binocular winning or being "alpha". It's a blend of different binos being better at different activites or used in different settings. For example I would rate
Astronomy
SF 8x42 10/10
EDG 8x42 7/10
Birding
SF 8x42 5/10
EDG 8x42 9/10
