Which bodies?  Neither Nikon nor Canon use the same
metering pattern, algorithms, or look up tables in all
their bodies.  I find the evaluative metering of the
EOS 3 to be brilliant in all but extreme conditions
(and that's what spot metering and a little experience
are for).  

But the evaluative metering in the Elan II has always
disapointed me--doesn't work very well at all in
backlit shots.  (And before all or you Elan II owners
start screaming, I own one to, and like it a lot.  But
shoot some backlit shots on slide (NOT negative) film
and see what you get.)  

The Elan IIe has 6 metering areas, the Elan 7 has 35. 
There's a bit difference right there in how many
variations they can detect.  The number of "scenes"
the camera compares to varies from body to body, too.
In both the Nikon and Canon lines.

So you can't really say which brand is better, or how
"good" it works without being more specific.
