It's all about the quality of the work. The glass is of lesser concern, since most are decent.
I had a windshield changed one time, by Safelite, and the installer cut the side moldings off, since they had a strip that goes down into the urethane. I specifically mentioned that I wanted new moldings when quoted, but the installer either wasn't told, or ignored it. They came back and redid the job. The windshield had to come back out, and the more you do that, the worse the job gets. 2nd time was a little better, but now the top molding didn't fit right.
