Which inauguration is more impactful? Kennedy or Obama?

This is more for people who lived through Kennedy's inauguration and presidency. Do you feel that Obama's inauguration and pending presidency is more historic and impactful than John F. Kennedy's? While Kennedy brought hope and change to millions of American, I don't think he compares with the feelings of hope and the longing for change that Obama is bringing to the county (especially after what we've been through). Your thoughts.
