Have been using it for a couple years. Before that I was using Fira Code/Mono which was also fantastic. However, once I got used to the condensed Iosevka, all the other fonts just felt loose and not space efficient enough in my IDE and terminal.

I am the opposite. I have CommitMono, Iosevka, Source Code Pro installed, but I always come back to Fira Code/Mono. At the same overall density of text, I find that I can skim through the text faster when the font is wider.

It's interesting how personal font choice (among many other things) is!

Exactly the same for me! I love it for the terminal especially
