Put me down for Gears 2 for sure. It will be more accessable and in the 1-2 weeks reviewers have to play the game, and write a review...it will score better.
That and the fact that Insomniac have yet to have a AAA game this gen...
EDIT. Actually don't put me down for anything. I don't think either will be be all end all game of 2008 so...
