I really like Berkeley, JetBrains Mono, etc, but at this point I simply can't move away from Fira Code. It's, like, what code looks like to me at this point.

Is this the recommendations sub-thread? Inconsolata is the best i've used.

Intel One Mono. Not extremely different from Berkeley Mono it looks like but lower x-height, higher line height, more space around letters, and a number of smallish differences (mostly in the lower case letters and numbers and round dots instead of square). Intel has the extra visible {} and non-continuous % while Berkeley Mono has the funky @.

Fellow Inconsolata fan here. I have to say this is probably the first time I'm considering switching and maybe even paying.
