Iosevka and its family are a true masterpiece. I used it as my main primary monospaced font since it's so clean and pleasing to the eye.

I now switched to Ioskeley Mono, which is an Iosevka configuration made to look similar to Berkeley Mono:

Either the Iosevka originals or Ioskeley are gorgeous fonts. I'm grateful to its creator.
