I know that Debian has their own independent rating system, if you will. It's just that I trust the PG group inherently.
PG releases involve a deep testing cycle among serious users of the software. The Debian testing cycle ... well, PG isn't exactly the "fave rave" in the Linux world, and I would be thoroughly amazed if the Debian test cycle for PG was even 10% as relevant as the PG test cycle which involves folks with terra-byte scale live installations.
