I subscribe to the World War Z zombie model (the book, not the crappy movie), and look to natural barriers and population density as key elements.

Hawaii would be #1 on my list simply because Oahu is heavily armed (military bases) and geographically isolated. The remaining islands are toast if the infection spreads there. AK would be #2 given the military assets there and the archipelago at the southwest.

Any city with more than a million people likely would be toast. California would try to legislate the zombies away, then try outreach programs before San Francisco was consumed. San Diego might survive but for the LA zombies and the Tijuana zombies surrounding them.

And if those military assets are zombieized?
