Best Romantic Dynamic?

Getting a friend to decide which pair they liked more between Xayah/Rakan and Lucian/Senna quickly devolved into swapping couples.

I stated Lucian and Rakan would be an opposites attract duo, the serious and straightforward Lucian and the carefree and flamboyant Rakan would be a good clash of different personalities

My friend said Xayah and Senna would be trash two emo girls, and also thigh sandwiches.

I think we all know what the right answer is
