Zhujiajiao or Zhouzhuang??

Hi, is it possible to visit these two towns in one day from Shanghai?
actually if compare two of these, which one is better where have more nice scenery?
Which will you recomment to go if only can choose one.
From Shanghai to Zhouzhuang is nearer or from Suzhou to Zhouzhuang?
My trip route will be first at Shanghai - Suzhou - Wuxi - Huangshan - Hangzhou last to take flight,9days.
