Mildly better. An obese person should not be running in any case, even if they're able from a cardiovascular standpoint, the impact that running & jogging has on joints is unacceptably severe until a person reaches a normal weight range - even the ubiquitous-in-the-US 'Overweight' status is pushing it. Ellipticals, cycling, walking, leg lift machines, etc are much better.
