Depends on the writer.
Why?
Because its the writer writing the story
Vampire Lord might beat it if they are also a Transcendent Vampire. Otherwise the Transcendent Ghost would win.
Transcendent > Lord in the power hierarchy, and ghosts seems to beat vampires due to their spiritual nature (much harder to hurt and even more so to kill without the right preparations).
But yeah, while their logic may be hard to grasp sometimes, writers always have the last word.
