This debate will run and run. It's the same with any car/vehicle that has 2WD and 4WD options: some folks like the idea of having 4WD/AWD as they feel it makes the vehicle better to drive. You hear things like "it feels more sure-footed" or "planted". I don't really know what those things mean, TBH. But they're entitled to their opinion and how they spend their cash.
We have both 4WD and 2WD vehicles in the family 'fleet' at the moment but like most of us I'm never going to get to do a back-to-back test drives between different options of the exact same vehicle. A 4WD/AWD system is heavier for a start, so the thing is bound to feel more 'planted' I suppose.
But in normal conditions, ie not in snow, mud or on a race track, when driving a vehicle with selectable 4WD I've never been able to tell whether it's switched on or off.
