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!
Try Hack. I've tried many including Jetbrains Mono and Fira Code. Both are really good but I drifted back to Hack. It just hits a comfortable place for me.
Maybe I just need more time getting used to them, but I just tried installing JetBrains Mono and Hack and switched between them + Fira Code a bunch and I still prefer Fira Code.
