I guess it's arguable whether it's worse or not, but CO2 doesn't typically kill any wildlife whereas oil spills do. There is a certain percentage that is leaked from every pipeline in addition to the large leaks that occur during tanker and drilling accidents. Even a small percentage of the large volume they extract is a large volume to pour on the ground. I'm not sure why you think the concentrations of oil in the soil occurring naturally approach even the smallest pipeline leak; would love to see some sources though if you have them.
