PyQt or PySide - which one to use

I started learning a bit of python and would now like to toy around a bit with gui-building. Qt seems to be a good choice because of its cross-platformishness.
Now there seem to be two bindings available: PyQt by Riverbank Computing and PySide, originally developed by Nokia.
So which one should I choose? All I can find are two year old feature comparisons, but what differences are there nowadays?
Which one is easier to use, has more/better documentation? Are both still in active development?
Licensing isn't of much concern to me since I don't intend to write commercial applications.
