I would go with Section 5 Row 3. Section 210 Row M is all the way at the very top of the arena in one of the last rows of the section. It also has a side angle of the stage so it will not be looking straight at the performance but instead will be looking from the side. Section 5 Row 3 is in the floor seating area and will have a great view of the stage. The only problem with sitting in floor seats is that there is a chance that the people sitting in front of you could block the view because there is no elevation as you move back through the rows. I think that in this case it would be worth the risk because the view from Section 5 is a lot better than the back of Section 210.
