He's worse for wear, but he's a SURVIVOR!
Well, a survivor of sorts perhaps but he is still subject to the B-man's fits of pique and the ever-present "Willie-beater". And you never get the idea that Willie has much of a life outside of the Old House.
My vote goes to Professor Stokes, who has always kept his head when everyone else has fallen to pieces. One reason for this may be the fact that he lives away from Collinwood and the Old House, and that he clearly has a life apart from all the crazy, supernatural goings on. His is the voice of reason in the chaotic, unpredictable world that is Dark Shadows. If I were to choose one ally in the DS universe, I think I'd choose the good Professor.
Of course, one can argue that the only way to stay sane is to stay away from Collinwood as much as possible, although that hasn't helped Joe Haskell or the Jennings brothers very much.
As for Julia, she is a survivor too, but her emotions are too tied up with Barnabas for her to have done quite as well. At one point she is even becomes one of Barnabas's victim's, bite marks and all!
Ah, the things we do for love!
Mrs. Johnson has fared better than many of the others, but even she has been scared out of her wits from time to time.
POSSIBLE
SPOILER:
In the end, one can argue that the biggest survivor of all among those at the DS epicenter, is Barnabas Collins, who has weathered vampirism, monsters, Leviathans, possession, curses, parallel time lines and emerged perhaps still a bit eccentric, but ultimately human.
