QThreads are better integrated with Qt (asynchrnous signals/slots, event loop, etc.). Also, you can't use Qt from a Python thread (you can't for instance post event to the main thread through QApplication.postEvent): you need a QThread for that to work.
A general rule of thumb might be to use QThreads if you're going to interact somehow with Qt, and use Python threads otherwise.
