I don’t know what’s with this font, but I can’t get away from it. I tried Monaspace because it looks really nice, as well as a few other programmer fonts. But DejaVu is just so sharp and readable, and it makes the code look slightly less busy.

A lot of modern fonts don’t look that great when not on a HiDPI “retina” display.

DVSM is timeless. IMO Hack makes a few subtle improvements like the zero, i/l, and some punctuation characters
