Wolfox

I've been watching hayate no gotoku recenyly and having seen this example, as well as many other examples, if a butler's expected power level, I can come to only one conclusion

Ciel would win

I would say Sebastian tbh. while he has limits, those can hardly be reached. and that's using Demon Weapons. Alucard doesn;t have such weapons, so really hurting bassy would be a nice challenge for him. and the only thing sebastian can;t do is eat ciels soul, soooo :/
