Never been to either place but I have driven all over mainland Europe (Germany, Switzerland, Austria, Italy, Czech Republic) and would have to go with the Hague. You can drive on the same side of the road in the Hague and you do not have to fly everytime you want to go visit another country. The Autobahns rock (especially in Germany where there are no speed limits) and the Eurorail passes on the trains can take you anywhere you want to go.
