Wikis features when having an Enterprise wiki Vs having a wiki page library

I am reading about wiki in SP2013, and some tutorials talks about Wiki pages when creating either:-

1. Publishing site ------> enterprise wiki
2. Team site-----> wiki pages OR wiki page libraries.

But I cannot figure out what are the major differences between the two wiki pages from the following perspectives:-

1. End-user perspective, mainly the capabilities within the wiki pages
2. Administrator perspectives.

Thanks in advance for any help
