http://jntlesnev5o7zysa.onion seems to be the official one, according to https://twitter.com/tpbdotorg/status/203221129513545729

Yes, but:

1. That tweet is from May 2012.

2. The other URL is in the address bar in the screenshot on the Pirate Browser web site. The screen shot has a time stamp of August 2013.

So the first URL was probably the official one in 2012, but it has possibly been superseded by the other one.
