First off please do not mark this topic as a duplicate. All the relevant threads are years old. I would like updated information.
What are the pros and cons of the following libraries? 
I am aware of:

PyGame, seems to be the most popular but the website is full of
broken links and no news in awhile.
Cocos2D Python, Seems good as cocos2D is all the rage right now.
Almost no support though and the stack overflow pages only seem to
get a post every couple weeks.
Pyglet, This is the only one I never tried as Cocos2D seems to use
Pyglet. Seems to update more then the cocos2D python stack overflow
but less then the pygame.
Other? Rate a better library!

I am looking for information on ease of use, preferably pythonic and up to date. But perhaps most importantly active.
Pygame and Pyglet are definitely on the radar.
Pygame
Great, popular game engine. No support for a variety of file types. But it's no longer maintained.
Pyglet
Very powerful, high support for many files. Thorough documentation. OpenGL support, intuitive.
Cocos2D
I really feel that Coco2D is just an unnecessary medium to use the underlying Pyglet engine.
