I need advice on where i should deposit my miles after attaining top tier status on QF.

(1) What is your home airport? (SFO, SCL, London LHR, HKG, Singapore SIN etc.)
Reply: SIN, CBR
(2) How many miles do you usually fly each year & in what class? (<25K, 25k-50k, >50k)
Reply: >50k, Mix of W and J
(3) What types of fares do you usually buy ? ( First, Business, Economy etc.)
Reply: Business, Premium Economy
(4) Can you choose your airlines and/or, class of service?. Do you travel for work and/or pleasure?
Reply: Mainly pleasure, most probably on CX and QF
(5) Which routes do you fly most often (US Domestic, Transpacific, Kangaroo, in Asia etc)
Reply: Asia - Aussie, Asia - LOTFAP, Intra-Australia
(6) Do you have FFP status of any kind in OW or other airline at present? What is it? Do you have any miles banked in a FFP? (AA Executive Platinum, QF Gold, UA 1K, LAN Comodoro, etc)
Reply: QF Gold (turning platinum soon)
(7) What is most important to you in a FFP? (upgrades on travel, priority services when flying the airline, extra baggage allowance, good award redemption rates, better award access, free - discounted lounge access, etc.)
Reply: Good earn and burn rates
(8) Preferred Airlines
Reply: CX, QF

Now I've shortlisted a few FFPs for consideration

AY plus - for its lifetime platinum status, but that requires lots of flying.
AA AAdvantage - Impressive earn rates and burn rates, possible EXP as well
MH Enrich - Impressive burn rates - possible platinum as well

Being based in asia, MH should be the obvious choice due to the proximity, but why not CX MPC, because it requires an insane amount of spending to get MPC Diamond. AAdvantage will be good for intra asia-pacific awards in J and the earn rate for EQM/EQP is 1.5 for W and J, making qualification for EXP fairly easy.

Open to suggestions!
