Vi is the editor of the Unix programming environment (among other things the shell). Emacs is a shell, that introduces a different kind of programming environment. The OS is still Unix, it's wrong to say that it is it's own thing, but you relate to it differently, but neither is inherintly "better" fit for *nix in the abstract, it's just that the shell is more popular since it was historicall the default UI.
