If I were looking for a new stand, I'd ask specific questions for myself.

How big am I and how big is the seat? How do I like heights, and do I enjoy sitting on the end of a "diving platform." Maybe I like something surrounding me a little better.

Some stands are for small hunters, who might only stay in the tree for a couple of hours. Make sure you look at the weight of the treestand. My max is around 20 or 21 pounds, for my body size. I carry mine in and out. That's one reason I've used it for nearly 15 years. It fits me and I keep it in good shape.

Never used the summit, but there are things that I like about them.

The major recommendation - fit you to the tree stand. Not the otherway around. Tree stands are usually not for every hunter.
