Have you ever thought about why your parents are the best relationship despite how different they are

Have you ever thought about why your parents are the best relationship despite how different they are? My mon and my dad are the best parents in my life, but I prefer my mon. Looking at the relationship between my parents for years, they have many things in common but others totally different.
My mon is a quiet person and my dad is totally different. He is very strict and also very organized. My mon likes to take care of the functions of the home. My father in the other hands is the head of the family. They are completely different in their way of thinking. My mon like to do exercises every day to have a healthy life and my father prefers to listen music. Despite of the differences they have a good relationship.
My mon always helped me emotionally, spiritually and professionally. On the other hand, my father has been a workaholic person who has never spent time on my personal things. Mon is more affective in her feelings. Whenever I had to make a decision in my life, my mother spends time with me trying to explain what is best for me. When I had to decide what career to study, my mother always thought about my future, my father has always been the person maybe a more realistic person.
