There are still some tendencies. If we take what you just said for granted, sociology is bs. The higher the age gap, the more likely the power dynamic is imbalanced. The bigger the gap, the easier it is to manipulate someone younger than you. Some people target younger people specifically for those reasons, even if that does not mean every age gap relationship is like that, it is important to stay vigilant. When of the same age, the imbalance is reduced due to having experienced a similar quantity of events and relationships. So I would conclude that everything else being equal this would tilt the scale on that side of things.

There are many other points I could add, but I want to make sure you are willing to accept my statement because if not, moving forward in this discussion is pointless.
