For me personally, AWD is less about winter driving safety and more about driving performance and enjoyment. RWD/FWD cars just aren't as fun to drive more aggressively within wide safety margins.
I think most "car guys/girls" would say the opposite, at least for RWD. RWD is more of the "fun to drive" precisely because the safety margin is smaller. It's the driving dynamic bandwith, whereas AWD won't let you get as squirrely.
In terms of max performance, without "fun" in the equation, yes, AWD is generally superior.
