Fira Code

Here is a nice tool that shows 2 mono fonts and you pick the one you like best. Until you end up with a winner: https://www.codingfont.com/

(I use Brutalist Mono myself)

I use Fira Code. It looks great and I really like the programming ligatures.

Try JetBrains Mono too.

Source Code Pro

Have a look at Intel One Mono. https://github.com/intel/intel-one-mono

I use the Iosevka Term Nerd Font in all my stuff

Comic Sans is the answer.

I like the Hack Font family. Doesn't have any problems with 0/O or I/l and displays äöüß fine for me

Fira code or iosevka.

I’m here to throw Inconsolata into the mix, though I use Fira more frequently now from a compatibility perspective.

One that I haven't seen here is Operator Mono. I use it everywhere I need monospaced fonts. It's paid, but since I don't need another font ever, it's worth it.

Intel One Mono. It looks bizarre at first but it grew on me really fast and replaced Jetbrains Mono which I had been using for quite a while.

Comic Code

Ubuntu Mono.

I think it has support for most special characters, but some of the weirder symbols aren't there like a handful of IPA characters or emojis.

But you can always get backup fonts on your system just in case

Dina , it's a bitmap font and there's a TTF version as well.

It's one of those things where I'm just used to it I think. The bitmap is sharp and everything else I've tried feels blurry or heavy.

Hack within the terminal and Consolas for all my IDEs

Hasklig.
Which is Source Code Pro with ligatures.

DejaVu Sans Mono

OpenDyslexic. Can read it at any size and quickly.

Comic code, I even paid for it. I find in easier to read. Maybe I'm dyslexic but have never been diagnosed or anything
