Three things I like about the Vader comic:
1. We see Tagge's starfleet that Motti mentions in Star Wars (1977).
2. We see Vader's starfighter squadron, something I've always been dissappointed that we didn't see in ESB, ROTJ, or the legends EU.
3. Tagge outranks Vader, which fits how Vader is presented in Star Wars (1977).
