I think I've responded before, but I'm a Marriott Platinum for three years who moved to Starwood.. They're ok (great customer service, Starwood Lurker is what all other customer service should try to be), but I found better hotel selection at Hilton. Both Starwood and Hilton comped me Platinum and Diamond and I in return easily made the top tiers in both.. while my Marriott Platinum card stays snugly on my desk...
