I've been to both. Italy is a tad cheaper, if you speak or read Spanish you can sort of intuit Italian, although it seems eveyone speaks English these days.
There are some very interesting cuisines in different parts of Italy versus what I feel is a more uniform cuisine throughout France. The Italian people seem more sociable. There is some incredible art in Italy's museums.
France has Paris (the Lourve); but Italy, in addition to Rome (the Coliseum), has Florence (Michaelangelo's David, the Medici thing) and Venice (Ponti Vecchio Bridge, gondolas, Venetian glass), both rate right up there with my favorite cities in the world.
Did I mention crusty bread, Italian wine, and pasta?
I have to add, though, both countries have a lot to recommend them!
