Twilight and Sunburst because I feel like their connection feels more natural and I can just imagine them constantly geeking out over stuff and him being the levelheaded one when Twilight has some nerve wracking princess duties to attend to
I ship one of my OCs, Flawless Fancy with Sweetie Belle because I only see her being shipped with Button Mash and she seems too mature for him. Besides the fact they barely know each other in the show.
