zsh is broken and breaks X times per year. It's annoying, really. I'm tired of wasting time configuring terminals time and again because the new version of XYZ package is broken.
Anyone who does not enjoy spending huge amounts of time trouble-shooting on the terminal should use bash. It's the default in most distributions, it supports all major features a modern shell should.
Never ran into any problems with vanilla zsh on Arch, Debian, or OSX -- just pacman -Ss zsh || apt-get install zsh || brew install zsh. What kind of problems did you run into?
