A paid internship with an unknown international organization or an unpaid one with the U.N.?

I’ll probably have enough to sustain myself for the duration of the unpaid internship but I’m wondering if it’s worth it. I mean they clearly state that we should not expect to be hired at the end of the internship nor are we eligible to apply for any position within the organization for a period of at least 3 to 6 months. And it’s unpaid! I will be almost broke by the end of it.

There is no guarantee I’ll get hired by the other company either, but they don’t have such restrictions… And the internship is paid.

So which would You choose?

What type of company is the unknown international organization, what type of profession are you interested in and how much does the internship pay?
