Why would you compare her to a 6* when she is at lvl 80 200% and don't add the extra 100% affection to any 6*. That reason alone is why you should not compare her to 6*
The reason I say this is because the blossom affection has been around longer.

Also to add this why not focus on HP on the Whale Airship. A lot can happen since you don't have control and if you do mostly basic attacks you will probably die at higher levels
