This is a good question. There is a thread somewhere that is for pictures from every person's seat, and that should be helpful. You can also check out the NYCFC Virtual Venue, which has panoramic photos from each section.
It's a tricky layout in Yankee Stadium. In my opinion, the seats along each sideline are too far away from the pitch. I think the best seats are in each corner, followed by behind each goal. My son and I went to the first game and sat in the front row of Section 208, and those seats were terrific. Only downside was being too far from the supporters section.
