The main reason for using (neo)vim is motions and text objects. Pretty cool to be able to type cxia, ]a, cxia to swap two function parameters in code. Or daf to delete a whole function.

Even just f to jump to a specific character later in the line, or t to jump up to that character are absolutely life changing.

I love love love editing HTML in neovim with the ability to do stuff like dst for "delete surrounding tag" or St<div class="something"> to surround the current selection with a new tag. I have yet to find another editor that can do stuff like that with just a couple key presses.
