Well, I can tell you I've been struggling with this same decision for a few years. This year I finally made the decision and am going with the front mounted blade. I'm waiting for it to come in. I don't know if this will be helpful, but I'll share my reasoning and you can take it for what it's worth. :2cents:
In the past I've used a front mounted blower on a little lawn tractor. I really liked the way you can just blow the snow out of the way and not leave snow banks on the side of the drive. I have a crushed rock driveway, so come Spring I did end up with a lot of stones blown all over the yard that I would have to power rake back onto the driveway.
I finally wore the thing out completely. It bellied up half way through one winter. I had a snow blade for the front of my ATV that I had never used, so I got that out an hooked up and have used that ever since to plow snow. I was trying to decide to go with a front blower for my BX or front plow for it.
Snow blower pros:
-Blows snow completely out of the way, no snow banks.
-Don't ever have the issue of snow banks or piles building up to the point it's pinching you off.
-Don't have to get the loader out to move banks/piles back if they do start becoming a problem.
Snow blower cons:
-Leaves rocks all over the place unless you have a paved driveway.
-Much more expensive (if you get the options which I would have.)
-Can get snow all over yourself and the machine unless the wind is blowing the right way (or you have a cab.) Wasn't ever that big of a deal to me.
-Slower to get the job done.
A plow will be pretty much the opposite of these. You leave snow banks that can get problematic if you get enough snow fall and/or you didn't push the snow back far enough in the beginning of the season. With a stone driveway you'll still end up with some rock pushed off into the yard, but much more localized and closer to the drive edge - easier to clean up. Much less expensive, quicker, and don't have blowing snow all over.
Having said all that, if I had a paved driveway I would have gone with the snow blower for sure (it really is nice to have that snow just disappear) - and I still may if I'm not completely happy with the plow after trying for a season or two. With hydraulic lift and angle I'm thinking I may be fine.
If I decide later to go with the blower, I figure I had to get the quick hitch subframe in either case so that's not wasted money, and should still be able to use the plow on occasion for light duty dozer type work. If I really don't find any use for it, I'm only out the $1400 for the plow itself and could probably recover some of that by selling it, though it's likely I'd keep it.
Hope I didn't make your decision any harder!
