Overall, I would rate CX quite highly, even near the service standards of SQ. However, cost cutting are starting to show, especially in the meals, but for the price of airfares they are offering, it was well worth the money. Hopefully I would be able to try out their new economy seats and IFE in the future, which should be much better than those in the old aircrafts.
