IIRC, Phil is 1 up or even when going head-to-head with Tiger. Two hall of gamers, two multiple major winners, opposing personas, and basically dead even when they've been paired together... smells like a rivalry to me, no?
I thought Phil-Tiger was great for golf, and I'd love to see another one emerge. As far as Phil-Tiger goes, it seems to me that Tiger has a whole lot more actual wins going head-to-head with Phil (most notably Masters 2001 and Doral 2005). I can't actually remember any Phil wins head-to-head against Tiger, with the exception of the TPC Boston a couple years ago.
