If you want something that you can carry in long distances, or even travel by air with, I think the Loc-On Windwalker is the answer. It is very light, and extremely easy to put up. It has a very small platform, but I've killed several deer from it on all-day sits late in the season where I was making a long hike in and planning to sit all day. Carrying a full-size stand through all the brush perhaps a mile? Not worth it. And that's where the Loc-On Windwalker excels. That said, I altered my Windwalker (I think I bought it in the late 1980s) by putting a lag screw through the base to help the base "dig" into the tree's bark a little bit more and make it more stable. I also replaced the top bolts on the frame with longer threaded bolts that would similarly dig in to the tree a bit. These adaptations made my stand more stable on the smaller trees I often hunt out of. That's another advantage of the Windwalker; it will work fine on small trees. I don't know if Loc-On has improved the stand in the 20 years since I bought mine, but mine was certainly money well-spent.
If you are looking for something larger and bit heavier (and extremely comfortable), the Lone Wolf Assault gets my vote. It would be harder to travel with, especially by air.
