1. Pandas is very easy to use (since it is a python library), and there are a lot of functions to make one's code easy, short and efficient.
2. Pandas developer community and support is extremely high, and almost all problems one may ever face is already addressed and solved on StackOverflow and GitHub.
3. Pandas integrate very well with other python libraries.
4. Pandas also contain functions for plotting graphs easily.
I like pandas than most because it is a very easy to use library where I can quickly set up an analytic workflow and drive results from having very easy to use data structures.
