Personally, I use Terminus in my text editor and terminal. Bitmap fonts just look much crisper and cleaner to me.

I have found that I dislike fonts that have overly squared-off corners, in which all the letters look so uniform. So, I just don't understand the appeal a lot of boutique "programming" fonts like proggy or monoid.

I tend to like monospace fonts with a bit more rounded corners, which to me gives them a bit more "character" (one could almost say quirkyness) and readability.

good examples of this would be Bitstream Vera Sans Mono, Monaco and to a lesser extent, Iosevka

Honestly? I always go back to the core MS fonts (Arial, Courier New, Times New Roman, etc...). I even use the Fixedsys typeface when coding. They're usable, familiar, and most importantly, look good at small sizes.

The downside is that an unusual renderings (e.g. Font size 17), they don't look great, but it's a small price to pay.
