It's more than keyboard shortcuts, vim has different sets of commands that can be composed to take different actions. Say, typing di" [d]eletes what's [i]nside a pair of ["] characters. Also vim is more powerful if used as a Unix tool instead of per se, it's more of a citizen of that ecosystem.

There are different paradigms in development environments, Unix+a text editor is one. There are also those like Emacs, Acme, and usual IDEs. One has to choose which is better for their use. Say if you're a Mac or iOS dev maybe XCode is better for you, but if you're writing C, Perl, Python, etc., Unix & Vi is a nice environment. If you're doing Lisp, Emacs is the best environment out there (though Emacs and Vim are extensible, so they have some tooling for all the languages out there).
