Like Bob said, sit on a drive both. Make sure you are comfortable with each/either of the dealerships. That should be a major factor in your decision. Because either tractor will do the tasks the same - though it looks like mowing and snow blowing will be the primary tasks.
Now I'll tell you how my decision. When I was looking I was set on a Kubota
B7500 (the current model at the time). I knew of both dealers but had never visited either, had the same level of comfort/discomfort with each. So that took the dealership out of the equation for me.
So now it came down to the tractor and the price. Originally the Kubota was cheaper, but after talking with both dealerships a little bit more and understanding the NH dealer's price aleady included tax and pushing him a little bit he ended up so close in price it didn't matter. Then throw on top of the good financing NH had at the time it ended up becoming cheaper - though not enough to sway away from the Kubota - hadn't driven either yet at this point as neither dealer had one.
Finally the Kubota got one in that I could drive. I wasn't happy w/ how it was laid how. So my bubble had been burst a little bit. Started reconsidering the NH. Really didn't want a NH because of the old Ford relationship (I don't like Fords -- though I know their old tractors are tough to beat). But after going and driving the NH 24D. I was in love. It started easier, smoked less, and was quieter than either the 7500 or the JD 4115 I was also considering (though only briefly because of price). I was also more comfortable on the NH and the NH just seemed more "modern." Coupled with the sloped hood and loader arms it was just awesome. But I still wasn't ready to give up the Kubota. So I went back and started comparing specs - yet again.
The NH loader was stronger and a little bit bigger. The bucket was made a lot stronger (in my opinion) and looked like it would hold more. There was more 3PH lift capacity on the NH. The NH had a few more ponies to help with running the attachments (I know not really fair as I could have considered the Kubota 2410). I also liked the pedal system better on the NH. Finally I liked the fact that the NH was the old style construction instead of the ladder frame on the Kubota. Just seemed like a better set up to me. Though I'm sure it is fine. Finally the NH's weight came into factor. I knew for finishing mowing lighter is better, but for almost everything else weight is your friend - especially loader & boxblade type work. The NH eventually won. Of course, these are all my opinion and others have obviously come to the opposite conclusion but YMMV.
Now as far as implements I use. I have a 5' box blade and 5' scraper blade I use w/o problem. I run a 4' cutter but wish I had a 5' in it. I also use a homemade trailer mover and subsoiler with it. I've also used a post hole digger with it. It has been a good little tractor.
