Jesus said, "My kingdom is not of this world," and "Render unto Caesar..." He never got involved in political battles and warned his disciples that "those who live by the sword will die by the sword." His final words in Matthew's Gospel are: "Go into all the world, making disciples... baptizing... teaching..."

Mohammed lead his followers in rogue military raids against other tribes; began slaughtering Jews almost as soon as he became a prophet; and encouraged his followers to be (literal) warriors for Allah. In his farewell address he said, "I was ordered to fight all men until they say 'There is no god but Allah'."

I think it would make a not insignificant difference if someone converted from following Mohammed to following Jesus, or vice versa.
