Zhujiajiao Ancient Town or Xitang Water Town

Hey,
I was wondering if anyone knew which of these two towns are generally better to visit. They both look amazing, however I am only in Shanghai for a short period of time.

When I say better, I mean: most scenic/beautiful, which is the busiest and will they both be flooded with tourists?

Also, does anyone know which is easier to get to from central area of the city.

Thank you,
Phil
