I seriously don't think that Chanel would allow their bags (whether from It or Fr) to be of lesser quality (france and italy are just really close).
My chanel shoes are made in Italy and the leather is BEAUTIFUL, my Louboutin shoes are from Italy and they're ALSO amazing, I don't own any made in italy bags (my chanels are made in france being located here)... but i'm pretty sure the craftmanship is just as good in france as it is in italy.
I would even say that tailoring wise, italians are probably better.
A big house like Chanel would not have their bags made in country if they thought the craftmanship was worst... seriously!
And as long as it's made by real people who know their job (whether in france or italy) you have good and bad, better or worst.
And seeing that Chanel expands to other european countries, I have to say i'm quite happy, it does create jobs for people in the rest of europe. They probably do so with the skins they buy, train the people and it's probably easier for them (saving on import export) than shipping everything to France to despatch later (sorry i'm that type of european citizen.)
