I also highly recommend PragmataPro⁽¹⁾ if you prefer more characters per line. It’s €199 for the complete typeface, but well worth it for something you interact with for many hours per day, every day. More than 9000 characters have been hand-optimized from 9pt to 48pt to guarantee the best possible readability. (You can start off with the “Essentials” variant for only €19, which is definitely a bargain!)

Goes on sale every year during Black Friday. 100% worth it even without the discount. Love Berkley Mono too.

Iosevka (https://typeof.net/Iosevka/) is a good free alternative that I like to use for online IDEs/REPLs and such. (Berkley Mono's contract forbids this kind of usage, which I understand, but I wish I could use it more!)

I presume you’re indicating what an outstanding bargain this is?

For something you look at the entire day? Every day? Seventy five bucks, once?

I have the full licence as I use this typeface professionally. It’s the best money I’ve ever spent.

Fonts are gear acquisition syndrome for software developers
