I agree that not all Amans are special or unique enough to justify the price points. For me, Beijing didn't quite allow us the peace and serenity we associate with Aman, so we'd opt for the Pen or SR or other typically 5 star hotel if we ever were to return. Venice has too much competition for the price point, so we'd get better value at the Gritti Palace being SPG Platinums--and likely comparable service since we're in a city and not spending as much time on property.

Amanjiwo IMO has no equal--it remains the gold standard for us in terms of almost everything. Amanpulo sounds like it has no equal, though I've not been there, but I can't imagine there being another private island anywhere with quite the repertoire of Amanpulo. We loved Amansara, and wouldn't choose anywhere else (even having checked out the much less pricey PH). We wished we could have included Amantaka with Amansara but time didn't allow that--but we definitely plan to visit in the future. Amankora has increased competition from COMO, in particular, but we believe this is still the gold standard in Bhutan.

Again, note that the more out of the way/remote destinations tend to be the Aman strengths where they really stand out from the crowd and offer something spectacular.

I do concede that there is significant competition now in Phuket and Bali, but I still believe that Amankila, in particular, offers the best of more remote Bali.

Amanoi in Vietnam does interest me, but I agree that it offers more of a beach only/short getaway experience, and less of a historical/cultural/UNESCO experience, much like the other properties you noted as being uninteresting. They also rank lower for us insofar as our interest goes.

I'm salivating over Amanoca outside Rio, however--since I love Rio so much and would love to combine them. I'm also salivating over the possible Gabon properties. And, of course, I cannot wait to get to Amangiri.
