A Giant priced at a level that competes with the boutique manufactures. Enough said. The benefit as others have mentioned, will be warranty and I'm sure it rides great, most bikes do these days.
And I strangely agree with Zaf on the PF bottom bracket. Last few bikes with them have been completely trouble free. I will concede however if I was given the choice of two identical frames, one with PF and the other threaded. Well, I'll take the threaded any day. But I'm not going to knock a bike off my short list for its BB standard. A drink bottle in the main triangle however...
