I agree that the advantages are not clear. Maybe this table of comparisons should go on the landing page: https://soupault.app/tips-and-tricks/comparison/

Most SSGs force a blog-oriented directory structure like assets/ static/ theme/ posts/ public/. But soupault only needs an input/ and output/.

Most SSGs convert markdown to HTML. But soupault is good at processing (or ignoring) any sort of source content, which is nice for excluding one-off pages, or parsing non-markdown, or using existing HTML content.
