I tried it again, quickly set it up in my terminal the "Iosevka Term" version, switching from Jetbrains Mono, and just don't understand how can people read this.
But, after using Berkeley Mono for three minutes, I switched to it everywhere in a week or so, and never looked back, or looked anywhere else, to be precise.
Yes, it's not free, and yes it's opinionated. I can say that my opinions align with that font pretty much. It's one of the things which I cherish like an expensive hand tool which really does its job very well and makes you happy with its presence.
I faintly remember about the though process of italics, but I don't remember it now. They don't look uncomfortable to me, anyway.
It's a modern yet period correct version of these older fonts, with proper character set support and love for details. It's so perfect for me, it becomes invisible, or as the Berkeley's page says: "It's boring. It's good"*.
Or as I mailed the creator after using it a couple of weeks: "It's so perfect that it transported all my computers to 70s, in a good way".
*: When I was writing this comment, I wondered whether I really set my browser's monospace font to Berkeley. It becomes that transparent after a while.
You can start with $75 package and work your way up if you feel like you need them.

It’s a real hackers typeface.
When I asked, somebody said it fits more characters in terminals and code editors. This sounds incredibly obvious, but for whatever reason that was eye-opening for me and helped me appreciate it a lot more when I tried it again. Now I can't use anything else.
I now switched to Ioskeley Mono, which is an Iosevka configuration made to look similar to Berkeley Mono:

Either the Iosevka originals or Ioskeley are gorgeous fonts. I'm grateful to its creator.
Why is ttc better?
