What makes you think that Search still runs mainly guided by page rank?
If that were the case then search engines would differ only on how big their database is, but unless you care about the long tail you wouldn't be able to notice much of a difference.
I don't work in ranking, but considering how the web has changed since the early 2000s I'd guess that page rank's quality has gone down as spammy websites and walled gardens appeared.
