Well, I'm no expert but I am a maple lover. The Sugar Maple, from what I know, doesn't have a whole lot of "cons". Except a lot of leaf cleanup after they drop for the year. I think however, that a lot of people get the Silver Leaf and Sugar Maple mixed up. If it's the silver leaf, it is probably one of the weakest of the maples. The wood is not strong like most maples. Very prone to storm damage. Proper pruning can greaty reduce the problem.
In my experience the Sugars have gorgeous orange leaves in fall and the Silver Leafs have more of a yellow. The Silver Leaf is so named because the back side of the leaves have a silvery appearance. Their leaves have more jagged lobes than a sugar maple.
