Orion testing
Under the new plan, Orion vehicles would primarily serve as escape ships for space station crews, and they could play a role in future deep space exploration. Lockheed has seized upon the latter possibility, drawing up plans to send several linked-up Orion capsules to an asteroid — a potential manned mission called "Plymouth Rock."
That's one expensive escape vehicle. Only allows for a crew of 4 compared to Dragons 7 crew capacity. Linking of the capsules together for space exploration is a limited advantage IMO compared to a single unit.
Are the Orion capsules reusable?
