^^ I'd say that title would go to the Royal Bank Plaza since it is golden and shiny in all lighting, while the Delta and any other ordinary glass building will match in only certain times/lighting, on an overcast day it will be dull too.
Regardless, it does look good in Bluedjay's picture.
Love the Delta. One of those rare instances where the end product turned out better than the rendering.
Unrelated but looking at the second to last picture, I wonder why they put that Ripley's sign so low (given there's ample space above). You can barely see it!
