What would happen if a newly turned vampire was ensouled?

Imagine one of the scoobies or a friend or family member was bit, in their deathlike coma Willow quickly ensouls them before they can wake up.

Would they just be like they were when they were human but now with a hankering for blood and super strength? Would the demonstration affect their personality?

With Angel and Spike hundreds of years of living without a soul would affect how they now act ensoulled.. but what about a new vampire with nothing to atone for?
