This rarely gets a mention but totally deserves one: Iosevka[0], a programming font with great ligatures, multiple weights, and customizable character variants to tune it to your preferences. It’s more slender than most blocky monotypes which makes it stand apart especially from more traditional choices like Monaco and Consolas.

I'm 100% in the Iosevka camp, especially the serif version with Iosevka Slab.

Looks amazing on a Retina screen, and it's quite compact on the horizontal axis, many programming fonts are far too wide for my tastes.

Just curious, which font size do you use? I kinda feel that small font size + serif make text unreadable.

I think it's perhaps small font size + serif + low resolution. Serifs can improve readability at times.

I used Iosevka for a whole year and it is one of the best fonts I've ever used, amazing quality. I only changed to Input because I wanted to have some variety.

Iosevka rocks. Regular, narrow width, nice looking both on low dpi and high dpi screens. It's the best for writing code IMO.

Iosevka converted me into a narrow width font fan, +1 for this suggestion.
