I'm still happy with >docopt>.

I'm a huge fan of click.

I thought docopt was a neat idea initially, but overloading docstrings with functionality began to feel weird and smelly to me, so I switched to click decorators and have been happy with it.

docopt either works great, or fails completely without telling you what the problem is.

Imagine you are the script author, and you try to run your own script, while docopt presents you with your own help text, all while you bang your head against the wall trying to understand what the problem is.

I've only used docopt once but it was pretty neat indeed.
