Front wheel drive.
Having owned a number of RWD cars (including BMWs) over the years, the chances for the rear end stepping out unexpectedly, especially on inclines is far higher than the issues that can be caused by a FWD with likely thinner tyres.
Even on all-season tyres (which aren’t anything near as good as snow or dedicated winter tyres) I’ve had issues setting off on inclines, having to resort to chains a few times.
Never had such issues with FWD.
My experiences include driving up the French alps for a healthy number of seasons.
