I don't care about experience before I start customizing because I am very certain that I will want to customize. A smaller configuration file does not benefit me at all.

I don't find zsh to be slow even on an older machine, so I'm puzzled what you mean by that.

Which only leaves the suggestion feature, which is interesting but not enough for me to pick up yet another shell with syntax that is even more different from the rest.
