Syd no question, when you consider current and potential endorsement earnings.
She is in the US which is a much bigger market than Norway. She has the good looks which will help.
Jacob has the looks also but there are probably more opportunities for women.
If you only consider a running and racing career, Jacob might have the edge long term. He could move up in distance and to the roads (he already has run road races). There are not many road opportunities for sprint and hurdle types. He might be competitive on the roads for another 20 years. It is harder to remain competitive as an older sprint type.
