For Angels fans: Did you consider John Lackey a real ace or over-rated?

I'm not an Angels fan, but I've always felt Lackey was a bit overrated. He's had 1 good year...but he's not an ace. But he's not the ace of the red sox, he's their 3 starter behind Beckett and Lester (come playoff time) and that's about what he is, a good #3.
