I honestly don't care if it's a human or a monster. Both can be interesting. Albeit, I myself like the more non-humans when it comes to various games and such, but still.
Nemesis and Jill Valentine are easily my favorite two, and I'd play as either. They're both great characters. Though it does help I know Nemesis more due to the movies, not the games, so I'm kind of used to him not being evil. To also be fair, I never played the video games(I don't like jumpscares), but I do have the Card Game(a build a deck type), and it's loads of fun. Yes, I always play as Jill~).
