France is out, they don't particular care for Americans; they're more formal in how they dress; if you need WiFi France is the best place for technology even in remote areas. If you're going there to participate in some sports, well France is the place for those sort of activities; France has the best food too but it will cost you;
Italy has just tons of tourists so it's always crowded, and the citizens that live in those areas are fed up with tourists, so they tend to put off tourists; go to a restaurant and ask for the check and it could take them an hour to bring it to you, they simply don't care, nor do they make any attempt to speak English. Lots of young children begging; cost to do anything there is astronomical.
So that leaves Spain, a quieter designation, want to serve their customers with really good service; Americans will find the English language is spoken there, the traffic is less congested, costs is the lowest of the three; they dress more casual and act more casual, they are a more relaxed people, but in that relax state they tend to talk a lot. Spain of the three is the worst for WIFI, you would be lucky to get any signal and when you do it's slow as molasses, but your in Spain, relax. The food isn't as good in Spain as the other two are but the food is cheaper.
Now obviously not all areas of Italy, for example, are going to be rude and busy, if you get away from the more touristy areas you will leave a lot of those issues behind in France or Italy. In Europe politeness wins the day, don't go there thinking you can shove your big broad American shoulders around, be polite and courteous...AT ALL TIMES!
Anyway, all of that is just my opinion, don't take it too seriously.
