Another data point for everyone to consider I guess.

I haven't been to either many times but I remember the times I visited both for the first time.
The SYD F lounge has a wow factor that left me very impressed along with the service and attention to detail and available amenities.

The first time I went to the DXB EK F lounge I thought wow this place is huge and then I saw the cafeteria and long wait for a shower... Staff were hard to find as the place was so huge and the food offering was very (for this comparison) uni cafeteria like. Comfortable place to wait for the next flight sure, amazing lounge to be considered one of the world's best? So far I don't think so.
