it depends on what your purpose is.

若你觉得SPSS会用得多些就用SPSS吧！

if you are in sociology or psychology or education or OB/HR in the business school, then spss is sufficient.

if you are in economics, most business disciplines, or statistics, then STATA is better.

spss is a dummy program, STATA allows your own programming.

also, STATA has powerful data management tools.
