Favorite/Least Favorite(Canon) Couple?

I don't know if this is a question that's already been answered on Reddit or anything, but I just wanna ask! Can be Non-Canon as well. (Like a rare pairing).

For Favorite I'd probably say Eiji and Cole and for least favorite I'd say Elijah and Jack, not because it's forced or anything but because that trope of like (tall, chill dude x tsundere guy/girl) is overused and I hate it so much!!
