If you go off road, launch boats, live in the mountains or high altitude, then 4wd would be a good choice.
I have almost been stuck off road in sand and been stuck in snow on a slight slope. The problem is, as long as you keep your speed up there is not a problem, it is when you stop. Going up a 6% grade freeway with snow on it was a challenge. CA drivers suck in the snow, and when I got caught in that snow I knew I was in trouble. Most cars are auto, and most drivers tailgate, so you get a stop and go condition. And being in first gear at idle speed, 4 mph was still too fast. I had to stop, once that happened my tires spun and no go. The people behind me and beside me could see I was having a problem. They gave me room, I gave it power, the truck drifted sideways to the crown of the sloping freeway, once I got on the shoulder of the road I gained some traction, got some momentum. I just drove on the shoulder, kept my speed up by shifting into the higher gears, got up to 5th gear, fish tailing all the way up the pass. I was constantly turning into the drift of the rear end to be in control. It must have looked like I was Cop's TV show being chased, from the other drivers seeing me go by at 30 to 50 mph on the shoulder. But that's what I had to do so I would not get stuck, just glad my wife was not with me, she would have been screaming#@$%!
