I prefer the Marriott lounge from a location/space prespective in that it is on the top floor (vs. 1st floor for Sheraton), has a small outdoor terrace, and is generally less crowded. The evening food offerings are actually pretty equal altrhough the Sherton seems to have more variety. As mentioned above, the best breakfast is actually the Flavors restaurant. Without regards to price, my strategy would be to stay in the Marriott and eat breakfast at Flavors as that is the best of both worlds.
