PR, in and of itself, will
not get a page to the top.
Look at these PR values of the top 10 sites for 'mail order
brides' on October 15, 2003.

All those PR5's beat the PR6 that came in 10th and even two
PR4's, (#8 and #9), beat the PR6 in tenth place.
Even Google says that PR is useless if the page doesn't
match a person's search terms.
PR is a measurement of a page's importance. It takes importance
and relevance to get to the top, imo.
I believe the greatest measure of relevance is anchored text.
To demonstrate this, take a look at mailorderbride.com, it's currently #3 in the SERP's for 'mail order brides'.
It does not have 'mail order brides' in it's Title.
It has no <H1> whatsoever.
It has a PR of 5.
It is not listed in dmoz.org,
and 'mail order brides' does not appear any where on the page.
Apparently, this webmaster has never even heard of web page
optimization, hehe, but he's got his page at #3.
If you follow the page's backlinks, you'll see that they are all
on the other site's homepage, (greatest PR), and they all have
'mail order brides' in the anchored text.
Of course, this is just one site, it could just be fluke.

PS: If you think that he's number 3 cuz the keywords are in
the url, nope. Do a "allinurl:mail order brides", without the
quotes, search and the page does not show up at all.
