Jurcina is outplaying morrisonn right now. But the main difference right now is that Morrisonn has proved he can play in the NHL where as jurcina hasn't.
Jurcina i like more, but i'm huge fans of both.
They are two very different types of defensemen, but it really does easily go to morrisonn, really only because of morrisonn's offensive potential. But jurcina is right now much better than morrisonn defensively and will probably be the better defensive player in the end. Morrisonn is no horrid defensive player though.
