If Jesus is a human being, then ignoring the effect he's had on the human race through way of religious influence...
on a personal level, he's pretty cool, but I'd wager they're plenty of guys like him in today's world, given the numbers... people that are pious and respectful, abstain from negative influences, humble, etc, etc. I mean, sure they're rare and you're not likely to meet one.... but I'd say more than a handful of people like this exist in today's world.
Jesus was a machine or tool for the christian change in that respect... by himself, christianity is relatively nothing... but somehow, something worked out... likely because constantine decided to adopt christianity as the official religion in Rome.
Given that; christianity is the effect of a couple major key figures, jesus and constantine...
Mohammed is the greatest guy to have ever lived; where jesus was like a pauper, mohammed was a friggin prince. He made vast sweeping changes in his time, and his direct legacy continues to grow; which can't be said for many other super conquerors of history.
