I have never agreed with the idea of Meiling topping anyone, especially Sakuya. Not because I think she can't but more because she doesn't have anything to prove. You know how Grant Morrison conceived of All-Star Superman with the idea of [paraphrasing], "If you knew nothing in the world could kill you, wouldn't that make you the chillest guy on the planet?" I imagine Meiling the same way.
Besides, there's no realistic way Sakuya ever tops Remilia (unless Remilia lets it happen), so at least let her be on top with Meiling.
