Trying to choose a browser..

So I want to use a light weight browser on a low spec machine to save on system resources. I also would like to follow a minimalist philosophy in general and minimize GTK and glib stuff on my system.

So far I'm weighing up these 4 browsers:

1: Luakit

2: qutebrowser

3: vimb

4: surf

​

I'm looking for recommendations as well as reasoning behind such recommendations. I know others like to keep their systems Qt free as well so I'm open to hearing peoples reasons for making such decisions.
