Yeah, Fira Code is an excellent font, and it is something I have used in the past. PragmataPro looked prettier to my eyes so I bought it, that's all. In fact, it's linked as an alternative on that Github page.
The condensed look and lack of interlinear spacing of PPro are a nice bonus, not that there aren't other condensed fonts. I suppose for intl use PPro might be nice too since it has 9000+ glyphs, and the dev is still adding more.
I've been doing Excel and VBA work for my internship this summer, and I have to say, I have an immense amount of respect for the engineers behind Excel. Excel is incredibly extensible, it has very nice built-in error handling for mangled data (but horrible exception handling in VBA), and overall it is simply a joy working with it.
Sure, it has some pain points, but for my use case (financial analysis), it complements Bloomberg very well. Bloomberg's Excel add-in is very well-engineered, and there is even a way to hook into Bloomberg through VBA. Cheers to the MSFT devs who crafted this stuff.
