First of all, I love the new look of the place; it needed it and has a completely different feel than before. Section 415 isn't where you will want to sit if you're afraid of heights. If there is one word I could use to describe it, it would be 'steep'. But you can see the entire floor and if you watch the Knicks play with any regularity, you will still be able to tell which players are which. They keep the seating area rather shaded but it's still pretty bright in there. There are armrests at each seat.

We paid $180 for two seats in row 5 and to me, I felt like that was a great value considering we were in New York and watching the Knicks.
Nets games are much cheaper and at the end of the day, you're watching the NBA whether you're at the Barclays Center or Madison Square Garden.
