What do you like best?
As a person with little prior programming experience, I have found Stata to be, by far, the easiest statistical software to learn while still having impressive analytical and reproducible capabilities. Stata is always adding analytical tools to its repertoire as well, so updates are worth getting.
What do you dislike?
Stata is prohibitively expensive for some individuals and companies, especially if it is for shorter-term or limited use. Increasingly, people are choosing R over Stata for this reason (although I find R more difficult to use).
Recommendations to others considering the product
If R and/or SAS are intimidating, but SPSS doesn't meet your needs, Stata is the program you need.
What business problems are you solving with the product? What benefits have you realized?
I use Stata for academic research, so it is my main work tool. Because most others in my field also use it, it facilitates collaboration.
