You seem to be confused about better in the objective sense. I am saying that designers make things fancy to get attention, especially from product managers. No claims about what is better need arise. From the perspective of the ux designer, they are doing what the market is selecting for and rewarding them for.
By analogy, You don't get to claim what is better in evoulution and natural selection. There is only what is selected for, which might not have any preference for what you consider good or not
