I don't know if I'm unique or something, but Radon is extremely painful for me to look at and makes everything harder to read. It makes me feel like I'm dyslexic or something. I currently use Fira Code and find that very easy to read and look at.
I've taken the Coding Font blind test tournament a couple of times the last years, and I somehow always end up with Fira Code as the winner.
Good suggestion. I like it a lot, but the Regular weight is still too bold for my taste. I'm using JetBrains Mono ExtraLight right now, so I just wish Hack had a couple lighter-weight options to try out.
It’s not just you. A few weeks ago I saw the “noble gas” fonts here on HN and gave them a try, ended up going back to JetBrains Mono. Still haven’t found one that can reliably displace it—even my prior daily driver, Fira Code!
