A few years ago I found comic mono and monofur for Powerline. I switch between the 2 when I get bored of one or the other. I decided I won't try any new fonts, it's a waste of time for me and I hate having too many options to choose from, not only fonts but basically everything else too, it's distracting. Same for my editor's theme, I switch between Braver's Solarized Light and Radical.
This way I can focus on coding and less on tweaking my environment.
