A slightly more considered answer. I dislike Simpson for its ugly brown colour, its soulless miniplaza on Bay, and the ugly transition from it to Burke's Simpsons store. I like Sheraton for its beautiful brown colour, and the way it neatly terminates vistas on the square. Whether FCP is attractive or not, a marble building should last more than 40 years. The Colosseum is still more or less standing, after all!
