It boils down to personal preferance. I like to use ground blinds if I can take the time to construct one instead of using a prebought setup, which isn't always possible.
If there is enough cover I don't mind a tree stand. A few years ago I sat in a tripod setup and felt like I was an orange cone sitting several feet up in the air. The timber was light enough that I might have gotten a shot out to 100 yrds. So in the future I will use tree stands for elevated positions.
