Hi Blur Angel, it's tough like what Raymond said. Italy is a country. Paris a city.
I think question is you should ask, what do you like to do when you go to different country? Both have lots to offer in terms of the art scene. My friends go to the Vatican City (where Rome is) once every so often, them being catholics.
Parisians are proud of their culture and language (thus their refusal to open conversations with an English phrase which others take to mean that they are rude - they are not really!); they take pride of their city. Whereas Italians well, um, let's just say, the streets of Rome are littered constantly and graffitis abound even on the ancient blocks of the Colliseum --> so that says a lot. Florence is much less polluted and I am thankful that they have retained the charming way of life. I love Italian food more than French. Well, I love provencal french foods just as well but that's way in the south of France.
For me, it's a toss. I was in Paris for a day but that was enough to make me and hubs go back later this year.
