> Scribus is very serious about PDFs

This is its killer feature! I've had compliments from multiple pro printers regarding my print PDFs produced with Scribus. Even though most usual PDF pipelines are Adobe based, Scribus PDF files are superior.

This is not true. Dont forget PDF is format developed by Adobe. There is no reason Scribus output would be superior. Its probably simply that you are more mindful, experienced, systematic user where adobe gets used by complete amateurs more often who have no idea about output.
