Which installment of the Heroes series had the best campaign storyline for you?

Perhaps, for me, the third game is also in first place; the fifth game has a decent plot, but, personally, I think it's not as good as the plot in the third game. P.S. And yes, I have to agree with bobchik; I didn't really get into "Chronicles" either, unlike the regular third game. My desire to play "Chronicles" disappeared after just a couple of missions, unfortunately.
