No, it’s more convenient. I personally would argue that AWD can make cars less safe because of the false confidence it provides.
The most important thing you can do with a car is brake and turn, as those affect safety the most.
All cars brake with all four wheels, drive type has absolutely no effect at all. All modern cars have enough braking power to slide on clean concrete, let alone snow and ice. The only thing you can do to improve braking distance is to change your tires.
Steering is only affected by drive type when you’ve got the hammer down, as you may be asking the front tires to propel and steer the car at once (this is partly why FWD cars often understeer). But in a snowy situation you won’t be driving flat out, so which wheels are driving will have little effect on steering, and zero effect if you’re coasting or braking.
What AWD is great at is getting you off the line in low traction scenarios, which is convenient. It also means that you can get an AWD car up to speeds that are unwise in the present conditions (remember that steering is two wheeled in almost all cars).
The only real advantage that AWD has is that AWD cars are typically heavier than their two wheel drive cousins, and weight absolutely confers safety in snow.
