Campaigns are irrelevant, sort them in order of the quality of their multiplayer.
I can't remember that much of combat evolved multiplayer, so I can't really rank it with any certainty. I actually enjoyed Reach's matchmaking slightly more than H3's, but I have too many fond memories of H3 custom games to rank it anything other than first.
