A little bit of everything

The problem is me and I can't be fixed

I have a serious question. In the mlb universe we have our very own love square. Ladrien, Marichat, Ladynoir, Adrienette. Ladybug is Marinette and Chat noir is Adrien. I've seen wars between each ship and I'm always confused because at the end of the day it's Adrien and Marinette. So my question is why? Why is it that each ship is viewed like they're ultimately different? For example: Kataang and Zutara. Katara is the constant, Zuko and Aang are the differences. In the love square Adrien/chat and Marinette/lb are both constant. Is it because each ship is like a different side to the characters or what cus I don't get it. If you're some who prefers Ladynoir over Marichat, vice versa and ect, pls explain your thinking
