This blog explains well how to use Ansible to configure Vim.

These are some of the many points in favor for using Pearl on this specific case (dotfile management):

• No easy way to include interactivity during installation
• YAML will become very tedious to maintain for more complex configurations
• No simple ways to use loops or if statements
• The same configuration could be done in Pearl with way less lines
• Installation requires backup of any previous vim config
  • Pearl allows to make append dotfiles from already existing ones thanks to the hooks mechanisms
• On the blog example the playbook must run in Fedora
  • Pearl allow to make OS agnostic configurations that works on Linux and OSX
