Everyone is different.
There's also a difference between hearing better and understanding better.
I hear very well, but not as well as a hearing person. (I can't hear a watch beep unless I put it to my ears.) However, I can't understand people with accents.
I know people who got CIs and hear better than me, but I understand things better than them.
So, which is better? As I said, it varies on the individual.
