I hunted from a tree stand for 20 years in Germany. It really made sense because of the dense population. Hunting with a rifle you were shooting down and not horizontal. Never bothered me, but the tree stands were all large, comfortable ladder stands permanently built onto a tree. Besides, you can shoot a rifle sitting down.
When we came back to the States and I started bow hunting, I naturally got a tree stand and found it awfully skimpy and I was uncomfortable with the height. My son and I got a couple of 2-man ladder stands - not so we could hunt sitting together, but so we would have more room on the stand. I found I still wasn't comfortable, even with a safety harness standing and shooting and shooting sitting down was pretty restrictive.
I hunt mostly from the ground now, but if I do go up in a stand it's with only the top 2 sections as mentioned. I know it's all in my mind. If I can stand and move comfortably on a platform 1 foot off the ground, another 12 - 14 feet shouldn't make any difference. It does though. I can work on the roof of my house as long as I don't go near the edge, but getting onto and off from the roof always raises my heartbeat A LOT!
I've found you can see a lot from the ground too
