I was just thinking about the age old anatomy question. Udders, Boobs or both?

Think about it if we go following direct anatomy there should be a quad crotch boob and while thats cute it sort of seems to get in the way of an anthro. So some give them 4 boobs or four nipples per boob and say that that is the middle ground, but that seems a tad excessive. and finally there is both, the crotch boob mixed with boobs and sometimes it works but most of the time it seems like someone was a little desperate to get their 6 gallons of milk faster.

So what is the proper ballance? Im not sure but I think it depends on the character, functon, interaction and uses. But that means it wont always be the same, which is ok but most people want this nailed down. So what is the solution to this old paradox?
