Looks nice - but unfortunately as someone whose day-to-day language is python, I'll give up my requests library [1] when you pry it from my cold, dead hands.
I'm the creator of unirest-python. I love requests and I think it's a great library, the Unirest libraries have been created to bring the same, easy, usage experience across different programming languages. They're a good fit for the 80% of simple consumption scenarios. We will improve all the Unirest libraries to make them a good fit for the remaining 20% :)
I don't like the idea of libraries competing with each other, I personally think they all get the niche of users who can decide which one to use accordingly to the problem they try to fix.

Not mine mine, it should be obvious. I'm not Kenneth Reitz.
In all seriousness, would be interested to hear about differences/benefits...
