For me, I have both but was disappointed with the plow as it rode on top of the snow packed down on my paved driveway... Just too light to dig in and get up the packed snow. Now if I were to get out early and plow before I had to leave for work it'd probably work great... But then again, what to do when it snows before you get home?
Another thing is my driveway runs right alongside my property line between the neighbor and I. And on the other side is a bank upwards to my yard, so I don't really have any place to push the snow.
Once I got a good blower it was awesome and I haven't looked back. As someone on here said, "with a blower the snow just seems to disappear".
As far as storage, I just unhook it on a skid sitting beside my garage. The skid is just about the perfect height to hook and unhook it. Yes, I'd prefer it under roof but that's a project for another day...
