I just played around with supertab plugin, but I didn't find anything particular. I feel basically the vim built-in 'complete' feature can do the same thing with <c-n> and <c-p>. Why supertab gained so much stars? I guess there must be something I wasn't ware of...

Supertab indeed uses the same built-in insert-mode completion as <C-n> / <C-p> (or variations thereof like omnicompletion, depending on the configuration). It's just that many users find the overloaded behavior of the Tab key (complete vs. inserting a Tab character) useful, probably because this is a common function in many IDEs and other editors.
If you already have the <C-n> completion ingrained in your finger memory, there's little to be gained from Supertab.
