The rent in those region from what I've heard from colleagues (I work as a SWE in Paris) is trough the roof. you also have to pay taxes in both countries, but compensation wise you'll still end up with a significantly better deal even taking into account things like cost of living. The commute is not better for me or my colleagues in the Paris region.
