I like Ceasar's or Bally's. Ceasar's if you want a nicer room. I like being on the boardwalk side rather than the Marina, more to do in my opinion. But if you only want to gamble and don't care about TR, I'd go to Borgata.
I was never really a fan of Trop, only go over there to use the comps that I must be getting my mistake. The Cuban and Italian restaurant there are both very good though.
