Yes, the difference is quite small – one needs to eliminate everyone, including the town, while the other needs to defeat everyone along with the town. The Commissioner, if he's not sure, will likely investigate rather than kill. He'll already have a clear result – mafia or not mafia. The Doctor and Sheriff remain. One can heal, and the other can block the killer or the victim (and thus save them from death). The Maniac isn't needed in the current situation, but you have votes on the Werewolf, Zubr, and Kitsune.

Барон "Vampires"
Отдай свои прошлые сны,
В сомненьях себя обрети,
В бешеном танце душа кружится!
Не думай, что будет потом,
Здесь и сейчас мы живем,
Стань хоть на миг сам собой, слышишь!
