Homebrew has been pretty great for me. You can install desktop apps with brew cask, dump your current app install state with brew bundle and then reinstall it all with one command on a new machine. You can even manage mac store apps with brew bundle with the `mas` app. It has been pretty central in my dotfiles script.
