I think that the best heart to use to perfectly revive someone would be to use Henry's heart. As his heart is the Heart of the Truest Believer, it is the most powerful heart. It combined with another heart would grant immortality. To truly revive someone Regina and Henry would both have to die at the very least. Regina's heart which was the true love of Daniel combined with the heart of the Truest believer should give it enough kick to revive Daniel.
