Westin is a much nicer hotel than Sheraton, with rates to match. Sheraton is more than 20 years old and it shows. Westin is only one year old and very stylish.
My experience as a SPG Plat is that I always get an upgrade at Sheraton, usually junior suit, never at Westin. They are owned by difference local owners.
