Both styles have their uses. If I could use either in any given situation then I would probably choose the treestand as it offers more visability and normally more shooting opportunities. However, there are many times when using a treestand is not wise or convenient.

I started hunting out of a commercial ground blind two seasons ago and it has opened a totally new aspect to my hunting. If you can afford it then I would get one of each and actually see for yourself which works better in your situation.
