#4 A more intimate atmosphere
By and large, NXT draws rowdy crowds to its TakeOver specials, and they never disappoint in being amped up for the action. The main roster crowds aren't always as electric, making some of their pay-per-views a bit of a bore to watch on television.
Of course, WrestleMania features fans from all over the world coming together to witness a wrestling spectacle, and thus it's virtually impossible for them to be a quiet crowd. That said, the arenas WrestleMania are held in are so large that they don't quite capture the same sound a smaller building would.
Emanating from the Amway Center, TakeOver: Orlando should have a pretty packed house. A lively audience makes all the difference and TakeOver could be more entertaining than WrestleMania in that respect.
