My personal favorite is Mononoki [0].

Oh that is very easy on the eyes, thank you!

Please, contribute your choices!

Also, not all are available via Homebrew Cask [0] although most are available, for example,

    brew cask install font-source-code-pro

Although I'm not aware why one can't search for fonts in Cask anymore (previously you could).

This is my fav: https://github.com/tonsky/FiraCode

It's nice, but not Sans Serif, unfortunately...

I like m+ https://mplus-fonts.osdn.jp/about-en.html

Currently the sample image for each font is small. Would it be possible for it to be more prominent?

Agreed, unfortunately Slant isn't really designed perfectly for this sort of question. We typically deal with things with more emphasis on the Pros/Cons like comparing Linux distros.

Very true!
