I used victor mono as primary font everywhere (vscode, idea, terminal) for very long time, and disagree with your opinion of its readability. It successfully replaced Fira Code to me. Anecdotal evidence, of course, but I want to counter the authoritative tone of your comment.

Although I’m using Iosevka now, Victor Mono was reliable work horse for me for very long time.

I found that font through coding font tournament style selector (codingfont.com).

I may miss some, but my history was Courier New - Consolas - Dejavu Sans Mono - Anonymous Pro - Azeret Mono - Fira Code - Victor Mono - Iosevka - Iosevka Slab, and if I will decide to go back, Victor Mono is going to be first choice
