some other things to consider...
I have an AWD Edge, and it handles semi plowed/ unplowed roads (under 6 inches of snow) much better than my Ranger on 31" tires and 4wd. the best thing about the Edge is as Lil Blue mentions, is the weight distribution. And I don't have to think about what I am doing. press the gas and go, turn the wheel to where I want and it goes. no brain power. Ice on the other hand can be a bit more tricky, but even on ice the Edge handles better.
The Ranger, you have to use your brain. coming to a stop sign and the grade in the road is a bit uphill, you gotta think and have the 4wd engaged. without extra weight in the back, the back end can kick out on you. No traction control or ABS, so that makes a difference. LSD makes it better though. Now as for having fun, the Ranger beats the Edge hands down in playing in the snow. and for the most part, if it is in 4wd, the truck usually goes where the front wheels are pointed, even if the back end is all over the place.
