I have never been to AC when they had a big fight on so I can't compare that, but a friend of mine swears by the Tropicana and loves the hotel and everything there.
The Tropicana ain't bad. I actually had one of my luckiest nights at the tables there. They have the IMAX Theatre too. Bunch of us got a nice buzz on and checked it out, they had a pretty cool 3d show there that day.
But the Borgata is still my favorite place to go when we're in AC. Didn't care for Revel at all. The place can't even pay it's bills yet and i read the other day they need another infusion of cash to meet it's financial obligations. The prices there are a joke too. I'll stick with the Borgata.
