The shape still depends on your preference. If you like something more simple, choose the Zhongni style (which is also the most common). If you like something more robust, buy the Fuxi style. If you like something more subtle, choose the banana leaf style. Girls use phoenix. Both Shi style and Luoxia style are good. I personally prefer Fuxi’s. Haha, I’ll give you a style chart for reference. The most important thing is that I like it and it’s comfortable to play~
