Emacs isn't superior to Vim in every possible way. I personally find Vim's modal editing hard to let go of. On the other hand, vimscript is an atrocity compared to Elisp. Vimmers have certainly managed to make some amazing extensions to the editor despite that fact, but no tool is perfect; the whole point of an extension layer is to make the tool work the way you want. The defaults aren't necessarily what everyone likes (or ought to like).
