That's not based on intuition, that's all based on prior knowledge.
And in none of those specific areas is there a significant difference
between any major camera brand. Although personally, I've always
thought Nikon's menus were quite sub-par and I can see why they
require that little "?" help feature.
Lets be fair, and you are being difficult. I ride on the fence of
both system, Nikon during the film days (from FE to F5) and Canon
during the digital times (1D2N and 1Ds2). When my friend bought a 5D,
and accidentally changed exposure compensation setting, he came to me
for help and for the life of me, couldnt figure out hoe to set it to
neutral, until I went online and download the manual...
Now, remember that I have not touched a Nikon body for many years,
and recently I borrowed a D200 and rented the D2Xs, and guess what? I
do not even need to refer to the manual for any settings.
