Vim is best modern terminal editor due to its compatibility with Vi and extensibility allowing it to rival Emacs. Be careful to avoid becoming too dependent on vimisms which can destroy the ubiquity of your Vi muscle memory, which is the single greatest advantage of becoming proficient with Vi in the first place.
Vim plugins are a great source of power when used judiciously. The leading plugin manager is currently Plug, which can be automatically downloaded and called on to install plugins when it is first launched in a way that does not interfere with other dotfiles that you might have saved in a Git repo.
