London to Paris - Which route?

bigH

I am doing a London to Paris ride later this year for charity - I can choose to do one of three routes:

London-Calais-Abbeville-Beavais-Paris

London-Dieppe-Lisieux-Vernon-Paris

London-Dunkerque-Arras-Compeigne-Paris

Grateful for any suggestions as to which is the most scenic route
