I can't speak for emacs performance on windows (you surely have very good reasons to put yourself through devving on windows), but if you're a big vim user I'd highly recommend looking into evil mode, to bring vim bindings into emacs. I find emacs native key bindings kinda stupid, and modal editing to be superior. There's also full emacs config suites around this, such as spacemacs and doom, if you want to explore how they integrate vim-ness into emacs. Emacs + evil mode has been my primary text editing environment for 7 years now.
