Well I stayed at the Hilton too on my first trip there, and also the Marriott. The Hilton is nicer hotel, but the area is very Modern (like any other city that has new areas), so for sightseeing maybe not best place to stay, although its not long walk to the central areas, I like the theater (live stage shows) area and cafes, which is not within short walk f the Hilton, closer to other hotels. But for Business, Hilton is very good choice.
