I have a land plane and it works great to level the ground but it only moves about the top 2 inches of dirt so if you have large and deep low spots on your lot then I suggest a box blade. You can get fill dirt and then use the land plane to level that out. To me its hard to get a box blade to really smooth out the ground but it's great for filling in low spots.
As for trail making the land plane will stick a longs ways behind your tractor so it makes it difficult to maneuver in the woods. I just knocked out a trail on my property. It is all in my woods. I used my grapple and artillian hoe bucket for this task. I do need to smooth out the trail and fill in holes where some trees used to be. I would love to use my land plane but I do not think I can maneuver it in there. I don't own a cat 1 box blade so I can't try that either.
