I have no CX DP to compare to, but I thought JX Y was excellent for Y. My comments from Dec 2023: "Long haul Y is excellent, one of the best I’ve taken across the Pacific (thankfully not too many). Brand new stylish cabin, bottled water + slippers + amenity kit + pillow and blanket at every seat, great edible food, same opulent bathroom fragrance and toiletries (lotion) as J."
