My experience is that they always get in way. Either they slow down the whole thing down, or it randomly freezes. Or the code-completion window decides to popup and it again slows things down.

For navigation I've used something like this since eternity: https://cloudef.pw/armpit/vim-bemenu-curses.mp4

For search, grep or ag will do. As for refactoring, personally I've never had the need for a tooling for that.
