SPSS FAQ: How does SPSS compare with SAS and Stata?: "Many people ask us about the differences between SAS, Stata and SPSS or which package is the best package. As you might imagine, each package has its own unique style and its own strengths and weaknesses. This page gives a quick overview of the style of each of the packages and the strengths and weaknesses of each, but this is by no means a comprehensive comparison of the packages. Sometimes people feel very passionately about the statistical packages they use; we hope most will agree that this is a factual and dispassionate comparison of these packages."
