In May, I flew BA from LAX to LHR in business. Yesterday, I flew ANZ from LAX to AUK.

BA: better business class bathroom by far. The forward/backward pattern is not my favorite. The person on the aisle has less room for storage. Staff were perfectly professional and attended to every need. Nice amenity pack.
ANZ: better food; friendlier service by far. The staff was there to attend to every need, including helping everyone to make and unmake the lay-down flat beds. When the flight was over, there weren't blankets and pillows everywhere. There was a storage area and the flight attendants took care of storing it all. Small bathrooms. Seat layout of all forward facing seats I liked better. Plenty of storage for the flight. Amenities minimal. One use only toothpaste, toothbrush, lip balm, hand cream, ear plugs, socks and blindfold. The card inside said something about hand wash but that was non-existent. I really like the bag that they were in. You could use it during the flight to keep track of your own things to make sure you didn't leave anything on the plane.
