I switched because of the massive control over the prompt.

I've currently got a three line prompt that includes info about my current repository: (git)[45afc8f02fef U master [origin/master ] ]

It lists type (git/hg) [checkout (U)pdated branch [remote branch] ]. It'll tell you how many branches different the remote is, what you are up to (staged), and colors.

That, better tab completion, and syntax highlighting of the command line are my killer features. I'm running a fork of the oh-my-zsh project, so you can see the features by grabbing a copy: https://github.com/srathbun/oh-my-zsh
