When it snowed recently in the UK, my Giulia was parked up in High Barnet, I work in London and I live in Peterborough.
The car was covered in about 2.5 maybe 3 inches of snow when I got to it (at the time I didn't realise it was illegal to drive with snow on the roof, so I didn't clear it, since then I got a notice from our lease company letting us know a few tips). Anyway, my route to the A1 was snow covered roads all the way, some 6 miles due to a diversion which took me down some very minor residential roads and into stop/start traffic, all I can say is the cars grip in A mode was superb, stopping and pulling away even on hills was no problem, it was very impressive.
Once on the A1 the roads cleared with occasional snow laying on the verges and central res, that was until I reached just south of Graffham Water and it started snowing very heavily and snow was settling on the road, it was a blanket of white, it went from full grip to slippy stuff in an instant, the car had an ever so slight wobble at the rear and I eased off and brought my speed down, no dramas, the car still felt planted, I know my front wheel drive Merc CLA would have felt more unsettled for sure... this experience gave me a sense of confidence in the car that was great, from there on in it was patchy all the way home, some 35 miles and I was quite relaxed when I got there.
In answer to your question though, it depends how far you have to go and what your options are if we get heavy snow, a light covering with short journeys on untreated roads I'd feel confident driving my Giulia, anything heavier or a long journey, I'd just stay at home and work, but I realise not everyone has that option.
