The airport is not in either city centers, there are more security checks, you have to check your luggage in etc... The door-to-door travel time is significantly more than 1hour for the plane. Also in my experience the TGV is much more comfortable than similarly priced airplane tickets. You can look at the landscape (unless you're traveling by night), you have more room, you can walk around etc...
