One could argue that for any "on screen" navigation (that is: moving to any visible character), there's nothing faster than vim's EasyMotion stuff, which has been adapted in Emacs as "ace-jump-mode". The latest version allows to jump to any character in any window / frame. I hardly "other-window" (C-x o by default in Emacs) anymore because it already takes two keys while in two to three keys I can use ace-jump to jump directly to any character I want, anywhere (instead of first doing C-x o then moving where I want to). For stuff that is not on-screen, then it's the good old ways.
