nyxt would be awesome when it has a decent browser engine. For now you cannot use nyxt on most regular websites (youtube is broken most of the time), They are working on moving it to chromium engine if I understood correctly. But yeah when it will be ready, it's the browser I waiting for the most.
For the Lisp fans, Nyxt [2] is a decent choice as well.
