You are right as the flying time is longer flying west owning to the headwind, especially during the winter period.
Personally I found fying from LAX to SYD have just about to exceed my maximum body tolerance to long hops and I would not be able to cope with the extra 2 to 3 hours with the EWR-SIN no matter what class of travel I am on!
