VA or ANZ to LAX

I've got a hectic month of travelling planned for July and just been told I have to visit LA too. I've checked pricing for a PE return ticket between LHR and LAX and have found that I can save about £480 by flying business class with ANZ.
I guess the obvious benefit is the flat bed that seems similar to the VA UC suites. Can anyone guide me which I should choose? I'm looking for comfort as well as TP and FC miles earning potential. I could be swung to stay with VA as I need 11 more TP to get to AU.
Any advice?
