It would fall harder, not necessarily faster. Acceleration by gravity is about 9.8 m/s/s no matter how much or how little you weigh, up until you get near terminal velocity.
Axion is correct, this is only true in the absence of drag (air resistance). This is a common misconception due to the fact that people remember basic physics problems but forget the assumptions and conditions specified in them. Your statement would be correct for falling objects in a vacuum but once you incorporate air resistance everything changes.

Here's a decent treatment of the topic from a source that most would consider unimpeachable.
