Having sat behind the basket on the top level, I can tell you that section 224 is awesome. Every play happens right in front of your eyes, no strain on your body. You can follow the basketball easily.

It's kind of dark up there and not as bright as the bottom level which I liked. Plenty of leg and elbow space; I didn't feel crammed into the fan to the right of me. But I guess that's all relative to the size of the person.
You'll be almost mid court and I've sat mid court before, the view won't be all that different at all. 224 has great seats no matter which way you look at it.
