I like how it's easy to use (no need to read manuals - just click) and how you can do many different types of analyses without having too much experience with these things. It has some quirks about its user interface but once you get used to using it, it works well for most tasks. And there are plenty of tutorials online if you have questions! I'm able to perform basic statistics such as t-tests and ANOVAs which helps me answer research questions more quickly than doing them manually in Excel or other software.
