I like trying new fonts for coding. So far I went back to my favorite DejaVu Sans Mono as I can legibly use it for coding at size 8. On my screen I can see 65 lines of code. When I tried Iosevka it does look good, but at size 8 it's legibility is not as good as DejaVu, it is about 20% more narrow (which is not too important to me), but it can fit just 60 lines of code on my screen. Less code and less legibility than DejaVu, so I'll pass. But I do love that there is a selection of high quality fonts for coding nowadays.
