With full control, and no negative effects? Definitely.
Standard "Natural" Lycanthrope? Yes, though a cautious yes. Full control of my wolf form, though no control over when I transform... Its a bit of a pain, but the advantages would make up for it.
Standard "Infected" Lycanthrope (No control at all). NONONONONONONONONONONONONONONO~~
Other wereforms? Being a werebear would be cool, and more people would be cool with it due to being labeled as the "GOOD" werecreature.
Actually that's another thing. If the Lycanthropy effects my morality (AKA: turns me evil) Then I would never accept it. Ever.
