having spent a lot of time on finding the right monospace fonts, one of the things i've noticed, that's particularly important in the context of coding is a visual symmetry.
some fonts individually have beautiful glyps or characters but when you preview them with blocks and blocks of code, there's a quirkiness that throws of that symmetry.
I'll give a few examples:
- Mono Lisa font https://www.monolisa.dev/ (truly gorgeous font)
- Recursive https://www.recursive.design/ (particularly note the casual axis)
I bring this up because Google Sans Code, is super quirky; preview a few characters individually and they look good; put it all together in real code, and it's just not as smooth visually.
