I can't give my vote to France because of the number of fields which are reserved for local based aircraft, especially in the area between Saarlouis and Strassbourg. Also, looking at the charts for that area, they have so much restricted airspace, it's ridiculous, to clear through the area you have to be max 800 feet above ground.
Having said that, the rest of the country looks easier to fly in so maybe it's just because of that particular area, my mind is prejudiced.....
