I've used Vimium for some months myself, and wasn't really happy with it. The reasons why mainly boil down to how VimFx/Vimium are quite limited in what they can do. For example:

- They can't change the user interface at all - qutebrowser has a much more minimal UI.

- They can't spawn external processes. In qutebrowser, you can simply hit ctrl-e while editing some text input, to edit it in Vim. Or you can use `:bind ,v spawn mpv {url}` to add a keybinding which spawns mpv with the current page, to watch YouTube videos in a real video player.

- As soon as you are on some special page (like the Chrome extension store, or the "new tab" page), they stop working, because they can't intercept keypresses there.

- In general, qutebrowser is much more configurable and extensible. You can easily integrate it with shell scripts via userscripts (https://github.com/qutebrowser/qutebrowser/blob/master/doc/u...), and soon there'll be a Python plugin API as well.

As for Vimperator - as mentioned, that probably won't be around in its current form much longer.
