I am on EK768 in J right now (JNB-DXB) and was handed Godivas. I asked about them changing and the lovely FA said they had the other one too, so I did a side-by-side comparison.
1. The Godiva box is larger, but the Coco Jalila feels a little more sturdy/solid
2. The Coco Jalila chocolates are wrapped a 2nd time inside the box in high-quality paper.
3. The size of the actual chocolates is virtually the same.
4. I wasn't able to notice any significant difference in quality and enjoyed them both.
all in all, not a major change and Godiva is still around as well.
Oh but the Coco Jalila seal is much harder to peel off than Godiva's!
