Most of vim is written in C with some interfaces exposed for scripting. Emacs is mostly written in elisp with some C code where necessary. The latter lends itself better to 'hackability' imo
For my own machines, I build emacs and import my saved init.el
On other machines, there is usually a standard vi/vim install that I can use if I am ssh'd in somewhere where I don't have my personalized copy of emacs. If I remember, I'll try to put these five lines[1] in the .vimrc for some saner defaults
