Both dramas involve image change. In Tadashii Ouji no Tsukurikata, a group of girls tries to transform the boys in their class into popular "princes". They call their project Ouji Producer (Prince Producer). Similarly, in Nobuta Wo Produce, two boys decided to turn a gloomy female classmate into a popular girl. Tadashii Ouji is more over the top and anime-like than Nobuta, and Nobuta has more character and plot depth. However, if you like one drama, you may like the other.
