Ballroom e Youkoso, Haikyuu!!: To the Top Recommendations
Each anime starts with the MC trying to get better at something they love to do. All of the characters in both the animes are sort of similar in some way, like in competitiveness. Each one deals with a competitive sport/ thing: volleyball and ballroom dancing, and both MCs have someone to look up to, in Haikyuu, it's the Little Giant, and in Ballroom e Youkoso, it's Sengoku. Overall, there're really a lot of similarities, despite the huge difference in the topics of the two anime.
