If you are collecting statistics on ediff usage on a one-frame setup,
here is what I have in ~/.emacs:

(custom-set-variables
 '(ediff-split-window-function (quote split-window-horizontally))
 '(ediff-window-setup-function (quote ediff-setup-windows-plain))

I guess people are not complaining about bad defaults because
they have customized them already.
