Adding to the list of 'this is what I am using', I have switched both terminal and code editor to Maple Mono[1]. Which, looking at TFA, seems to be somewhat similar in spirit as Atkinson Hyperlegible, although I haven't used that.

Maple has many ligatures, I personally like the hypervisible [TODO]. Overall I find it very legible, even on small sizes, and pleasing also for writing e.g. in Markdown.
