QR is the best overall in my opinion, but it is business only. The range of food and bathroom/shower facilities are particularly good.

CX is the second best overall but is the most comfortable for just relaxing and lighter meals. Unless the noodle bar is interesting to you then it would of course rank higher in the food category.

JL is the third best but is really just in place for its own flights and I see no reason to go there if you can go to CX unless you want some Japanese dishes such as Katsu Curry. Assuming they still have it.

WY is fine but don’t really care for it. The food is acceptable and it is an ok enough space. It was good for a PP lounge but as it relates to other OW lounges it is last in my opinion. It has a shower, but a pretty miserable experience compared to other lounge shower facilities in my experience. However, there are worse places to be camped out while waiting for your flights.
