Btw. I have the feeling a "Sith Lord" is not that high of a rank within the Galactic Empire governance structure. I remember in Episode IV Grandmoff Tarkin shouting at "Vader" without even using the Lord title and acted as if Vader is his Lieutenant. But maybe that's only for the original idea in "A New Hope". They clearly changed it in the later films.
I assume a Sith Lord is no rank at all in the Galactic Empire. After all them being Sith Lords is no common knowledge. I just read "Tarkin" and it was described quite well, that it was not clear what rank or role Lord Vader occupied in the Empire in the beginning. A close associate of the emperor? His right hand? The executive hand sowing terror in the ranks of the enemies...
The book was ofc. released after the film, but it fits into your second thought, that Tarkin is lacking the fearful respect, that they both have a long story together and know each other quite well. And they are both in the "inner circle" of the emperor. So of equal standing.
