[Star Wars] How do Vader and Tarkin compare in regards to rank? Does one of them outrank the other or do they have roughly the same authority?

They both seem to answer to Palpatine, so they seem to sit roughly in the same area in regards to the Imperial hierarchy. Does either one have any sort of authority over the other? If they were to give conflicting orders to a trooper, let’s say Vader orders them to shoot a Rebel while Tarkin says let them live, which order would take precedence?

It’s basically up to the emperor’s discretion. Vader has absolute authority when it comes to carrying out the Emperor’s orders, but sometimes those orders include yielding to Tarkin. They are not on the same “ladder” so to speak.
