Bkk hotels - sheraton or westin

[TripleZ]

I'll be in BKK for a very short trip in two weeks and am tossing up between the Westin and the Sheraton in Sukhumvit - I know they're both pricey but I'm a Starwood member and am trying to accumulate some stays in Starwood hotels in the next couple of months. Anyway, I see in the BKK hotels thread that both have gotten good reviews for being LB friendly...does anyone have a view on which is better?

I'm leaning towards the Sheraton but it's a lot more expensive - which generally reflects the higher level of luxury, I guess.
