If he only gets one of those which one is better, Overpriced or Overrated?
As someone who has been to Trillium and Treehouse many times I would say yeah, they're both a little overpriced. But they're both great and I don't mind paying a little more for great beer. It's not like I'm drinking a case a week so a little extra isn't going to hurt. I think Treehouse is a little more consistent in making great beer. Everything they make is great, whether it's a double IPA, IPA, APA, stout, brown ale, lager, etc. Trillium makes great stuff too but just not as consistently great as Treehouse.
I've had a few of Fox Farm beers on tap at a couple places in CT and Armsby Abbey in Worcester. They were very good. But I wouldn't say their best stuff is as good as Treehouse's best stuff. But again, I've only had a few.
