ITALY every time...
It depends what you like though. Florence and Rome are both beautiful (and romantic!). Both have lots to see whatever time of year - art and museums, little restaurants, lovely walks, a river meandering along. There are also shopping opportunities and both have good transport links with winter flights.
There will be options for all budgets too. We rented a little apartment in Rome and "lived like a local" for four days. (Obviously, a local on holiday!)...Bliss.
