I like very much https://github.com/sorin-ionescu/prezto
Is this similar to Oh My Zsh [1]? I personally have been using Oh My Zsh for years and I've always been a fan of it. I can quickly add themes and plugins and have my shell ready to go how I like it quite quickly on new systems.

zsh4humans is like ohmyzsh but much better IMO because when you first install zsh4humans, it walks you through a setup wizard that walks you through choosing your fonts, prompt style, completion style, etc. and automatically installs the appropriate zsh plugins and things like powerline fonts according to your choices.
