Best Place To Sit at a Mac show?

[Montclare]

So during the presale, I bought section 122, row 19 for the United Center, which is decent, but I figured I could always buy something else better if it came along. On Ticketmaster today, I bought floor 3, row 16. Now I'm trying to decide which really is better.

The plus about 122 is it's angled, and the negative about the floor is it isn't, so if I have tall people in front of me, I might not be able to see as well. The floor is closer to the stage though, plus if security is lax, I might be able to move up.

Anyone have any opinion about which one would be best? I have a picture with x's showing where the seats are.

Thanks!
