Other than having more obvious cleavage, I never actually cared about bigger boobs as it's still just a squishy motionless bag. Now an ass has tone and moves. When your hand is navigating a nice full rump, you can't forget that.
I mean, boobs are like the cafeteria of a hospital, you would never judge a hospital by how good it's food is as long as there's something. On the other pun intending hand, seeing a great ass is like seeing that they have the best specialist in whatever type of surgery you're getting.
