I didn't say that, nor do I agree. Sometimes AWD is, probably better, sometimes part-time 4WD is.
The Model Y is the only AWD vehicle I've ever owned and I got it recently and haven't driven it in tough snow yet. Having learned to drive in the snow in a RWD sedan, I'm still not sure how valuable it is to me. My mom, who has spent a lot more time driving in the snow in RWD vehicles than I have, chose her RWD Model S (great weight distribution and traction control) over her AWD Ford Escape to get to work in the snow and never had a problem. In snow, I generally worry more about stopping than going. AWD or 4WD don't help with stopping at all.
I've used part-time 4WD on multiple vehicles many times where I don't know of any AWD vehicles that could actually handle the situation, nor would I have felt comfortable trying (clearance is, perhaps a big contributor as well).
