I can't speak to what you'd get as Gold at Sheraton, but we recently stayed on my SO's HH Gold account at the Conrad, and what we got far exceeded what I got at Sheraton on my Plat stays (this could have to do with the fact that I'm a repeat customer and HH Dia, but I think there have been several reports of Conrad being good to Golds). IMO, there's a huge difference between Conrad Macau and Sheraton Macau, and I don't recommend the latter (based on several experiences as Plat). If you want SPG in Macau, I'd pick the Westin.
