I think it depends on a few variables. How much snow do you get in an average season? How much driveway do you need to keep clean? Is there parking areas that need to be kept clean too? How much walkways do you have?
The pros to plowing is it is fast and comfortable. You sit in a heated cab and move the snow much quicker than any other method. The cons to plowing is you need a place to put the snow. If you live in an area that gets a lot of snow, you will need dump zones. Places that you push the snow to get it out of the way. Just plowing the snow off to the sides of the drive in a big snow area (annual average around 80-90"+) is not going to work. The banks will get too big and you will slowly close in.
The pros to throwing the snow is you do not have to worry about banking of the snow. Just toss it off to the side of your drive. To some extent you can also direct where the snow is thrown (ie, in a clearing rather than on the house!). Another pro for a thrower is you can do walkways with it, so very little shoveling needs to be done (a real plus!).
The cons to throwing is it is slow. Whether it is with a walk behind or a tractor mounted unit, you can only go so fast before the auger and impeller are overwhelmed. Another downside is clearing a parking area with a thrower is no fun. Lots of quick up's and back's and just a lot of work for the results. Of course you are going to be out in the cold. They do make throwers with canopies, but it is to keep the snow from being whipped back into your face by the wind. You are still out in the elements. A blower mounted on a tractor with a cab is better, but unless you want to pay up for a nice heated cab, you are not going to be as warm as in a heated truck. The last downside that I can think of with the blower is moving the lighter snows (1-5"). You do the same amount of work for these small snows that you do for the 12"+ ones.
I use an ATV with a plow and also the thrower. For the 1-5" snows, I push the snow to the sides with the ATV and plow and then clean up the sides with the thrower. When the snow gets deeper than around 5" then it takes more time to plow and clean up than with the thrower alone.
Hope this helps!
