zsh is for vulcans. ;-)
Seriously:
bash 4.0 has some features previously only found in zsh, like ** globbing:
% ls /usr/src/**/Makefile
is equivalent to:
% find /usr/src -name "Makefile"
but obviously more powerful.
In my experience bash's programmable completion performs a bit better than zsh's, at least for some cases (completing debian packages for aptitude for example).
bash has Alt + . to insert !$
zsh has expansion of all variables, so you can use e.g.
% rm !$<Tab>
for this. zsh can also expand a command in backtics, so
% cat `echo blubb | sed 's/u/a/'`<Tab>
yields
% cat blabb
I find it very useful to expand rm *, as you can see what would be removed and can maybe remove one or two files from the commmand to prevent them from being deleted.
Also nice: using the output from commands for other commands that do not read from stdin but expect a filename:
% diff <(sort foo) <(sort bar)
From what I read bash-completion also supports completing remote filenames over ssh if you use ssh-agent, which used to be a good reason to switch to zsh.
Aliases in zsh can be defined to work on the whole line instead of just at the beginning:
% alias -g ...="../.."
% cd ...
