Iosevka is highly active and highly customizable set that I've been sticking with after a dozen terminal fonts switching. Every time I try a new font now, I go back to Iosevka. The narrow width makes it stand out significantly from the others and it's much easier to use when having multiple columns open on the screen. I highly recommend it.
You got me when mentioning multiple columns. My setup is that I have half of my external monitor with VSCode (the other half is the browser) and most of the times three columns in there - folder structure and two files on a split screen.
I compared Iosevka with the 3 others just as narrow fonts (Inconsolata, Nanum Gothic Coding, and Ubuntu Mono). Iosevka won for me because it is taller or bolder than the others (felt more easily readable in small fonts for me), but also because it is more unique in its shape compared to regular reading fonts — the “o” is more squared for example.
Thanks for your comment! I will change to it just now!
It is also my favourite. It's just narrow enough for using with multiple columns, but not too narrow that it affects legibility for me, and it's event customizable, for my nitpicky preferences.
