I haven't been to the United Center but have been to a number of shows on this tour in both Vancouver and L.A. I would recommend section 108. If you're in section 116, there's more of a chance you won't see the big screen and that's really part of the show. I sat behind the main stage during one show and couldn't see anything on the big screen but would have liked to. They spend a considerable amount of time on the e stage (round stage) and it looks like you'll have a nice view from section 108. Hope that helps!
