WeasyPrint implements its own rendering engine and might support some specific @page properties that Chromium does not but given the complexity of CSS and web browsers, you're generally better off sticking with Chromium due to its history.
Also – an added benefit is that we can use JS libraries like FontAwesome, Bootstrap, KaTeX, etc. which is where other HTML to PDF libraries fall flat.
