It's also possible that Integra from Hellsing could be a very powerful force in this crossover. She has the authority to command Alucard and the rest of the Hellsing organization. Her strategic mind and leadership could be the key to dealing with the Twilight vampires. She could manipulate situations to her advantage and use Alucard's power in ways that the Twilight characters might not expect.
Most likely Alucard. In the Hellsing universe, he is an extremely powerful vampire with a vast array of abilities. In comparison, the vampires in Twilight, while having their own strengths, seem rather weak when pitted against Alucard. He can manipulate shadows, has superhuman strength far beyond what we see in Twilight vampires, and his immortality is of a different level altogether.
However, one could argue that the Volturi, as a collective in Twilight, could pose a significant threat. They have a large number of vampires under their command and a certain level of organization. But still, Alucard has shown the ability to take on entire armies by himself. So even against the Volturi, he would likely have the upper hand. Plus, he doesn't play by the same 'rules' as the Twilight vampires, which gives him an edge.
