I honestly didn't mean it like that, but I can understand that it comes across that way.

A better wording would be "what advantage does this have over premake which is also Lua based".

Tbh, why does it matter what it's written in? Does it do the job?

Lua is the syntax in the build configuration file, not how the tool is implemented internally. It’s part of the developer experience.
