The RWD Model S handles extremely well. The AWD Model S holds the road like it's on rails. For my needs, my RWD Model 3 will be fine. AWD would have been better.
And I really doubt the few inches increase in stopping distance due to a few extra pounds of weight for the additional motor is as significant as the improved handling. Sometimes you need to stop quickly. Sometimes you need to swerve. Overall, AWD will be an improvement. Most folks don't need it, but where roads are slippery I would absolutely feel it's worth the cost.
