I guess that's why they give the big boys these jobs of running shows, not the fanboys.

That would be like Vader/Anakin surviving tossing the Emperor and then telling Luke, Yeah, I'm happy to see you and Leia, but I'm really always was and always will be a bad guy poised to take over the Galaxy. Won't happen.
You know, attaching a smilie to a statement like that doesn't make it any less smug or pejorative (
I'm going to assume that's why you put it there, since it communicates nothing otherwise). The idea that
your interpretation of events is right and
Starker's is that of a
fanboy is really petty.
And who are these "big boys" you refer to? And who is the "they" that give them these jobs? If they're the same "they" and "big boys" that gave us most of nuWho, then they're hardly in the position to be decrying anyone else as a "fanboy".
No matter how many ways you try to collate Star Wars and Dr Who, they're never going to come anywhere close to being the same, other than both being science-fiction fantasy. The Master is the classic, mustache twirling villain of the week (he is one of the original examples of this trope and a pretty unpretentious one at that). Vader neither affects the same kind of persona nor has a similar history (in any but the most superficial of ways). They're no more similar than any other two supervillains that you could randomly pull from any number of other sources.
Some of them have been redeemed, others have not. That you chose one comparison to bolster your opinion does not render any opposing analysis as puerile and erroneous.
