Which Halo is the best?

[chocoloco]

If you didn't play them all and in the correct order an accurate opinion can not really be made.

I liked Halo 2 the best as I thought it had a great campaign and the online play was a vast improvement over Halo:Combat Evolved. Halo 3 has a horrible campaign with online maps that are more boring than 2's. Combat evolved is a fun rental!
