I just wanna circle back a bit. Thanks for all the inputs. Based on that, I kept it upper case by default and allowed customization by setting the LogLevelCase option. github.com/xiaomi7732/P...#dotnet#csharp#buildinpublic
Normally I would argue that lower-case is proven to be better for legibility but in this particular case I think the UPPER case log-level is more easily distinguished vs the lower-case log-message. So... B. Tbf in a large log, I'd probably just scan for the colours though...
