I think those are pretty much it. Someone more knowledgeable (or those that own both) can drop in and add some more info.
I can also add that the handguard on the Pred has had some weight shaved out of it and yes, it is longer. In my experience, there were many requests for the longer handguard to give one more rail room and to accomidate newer shooting styles.
The Pred is less expensive. You can save some scratch towards the purchase of a quality optic.
Lastly, having shot and handled both, the Pred feels like a toy compared to the OBR. Unless you are planning on doing precision shooting or running a suppressor, the Pred is a great choice for your first rifle.
