I still use Terminus-9 with relatively big screen: 2560x1440, I tried different fonts like JetBrains Mono-13 but it doesn't feel good. Either fonts are too big, but good looking, or fonts are small how I like it, but they look horrible because of smoothing. Font smoothing algorithms are always flawed, you can't produce 0.5 of a pixel without making blurry edge. Terminus is very crisp and consistent at any resolution. If I had 5k or even 8k screen, then I bet regular fonts would be much more usable and beautiful looking at small sizes.
