Hi,
Also it will depend on where your departing flight leaves from,
Club autus being in the midfield terminal and Amex Centurion being around gate 40 in the main terminal
There is a review of Club autus here

I have been to the Amex Platinum section of the Amex centurion lounge briefly and found it to be quite good ( I had access to the Cathay First lounges ) ( looks on a par with the Club autus review)
Regards
