The scripting language is a joke, you can't compare it to elisp (gnu emacs is written in elisp, so the entire is available to elisp programs. VIM's scripting support is more like Visual Basic, the VIM authors decide which bits of the VIM 'machine' to expose to outside scripting languages.
But why run emacs if you already have an operating system?
