As far as I know, Qu Di is the best to use and listen to.

Qu Di has a sweet and melodious timbre, which is suitable for classical music, folk songs, traditional operas and other music fields. He has rich playing skills and can show various rhythm and scale changes.

Other common types of flutes include bangdi, zhongdi and treble flute, each with its own characteristics, but on the whole, Qu Di is still the most popular.
