What similarities do you see between the medieval european and japanese social hierarchies? which social class in either society, would you prefer to be a part of, and why?

A big similarity was that both medieval Europe and Japan employed feudalism; roughly summarized in Europe as: King --> Clergy --> Nobles --> Knights (Vassals) --> Serfs; summarized in Japan as: Emperor --> Shoguns --> Daimyo --> Samurai (Vassals) --> Serfs.
