I've not used it yet but if I remember well you can choose the POV as you wish. As such Imho is a bit superior to the avaible sources which unless you have multiple ppl streaming the run you can only get one POV.
Now I'll go into uncharted territory and say that streaming while progging is also a hit to perfomances, I imagine that while the recorder is recording you might not suffer from perfomance issue, but If someone has more ripe informations on this they can correct me
