Sunni is the correct one. The Prophet Muhammad (PBUH) taught us the way of Islam which is how the Sunni's practice it. After the Prophet Muhammads (PBUH) death Abu Bakir was the next in line to be the Muslim leader as ordered. The Shia's believed the ALI should have been the leader therefore started this whole split up. Plus Islam is about PEACE.. the Shia'as whip themselves because they killed Ali and they are punishing themselves. That isn't Islam. As Muslims we do not torture our own ENEMIES.. let alone ourselves! And last but not least. The word "Sunni" means "one who follows the traditions of the Prophet." I hope this helped.
