I think the better question would be which madhab is most closest to the way of the Prophet Muhammad PBUH. Don't get me wrong, they all are very highly regarded imams but we must make sure that we understand that they are not prophets and so they will make mistakes. Some of the issues in shafi'i are more closer to the truth than the hanafi, and some are vice versa. We should take those which are the closest to the sunnah and not do strictly follow a single imam. May Allah allow us to be true followers of his ONLY chosen one for the end times, the Prophet Muhammad PBUH.
