For me it depends on the objective. I still-hunt public ground quite a bit because I rarely ever target a specific deer on public. It's exciting that at any moment I can see a deer I've never seen before, and he might be a good one.
On private property where I have some target bucks picked out to hunt, I stay out of those woods as much as possible, and am very careful to not leave any more scent than possible when I am there. Still hunting would be a disaster on the private spots I hunt here in midTN because the privet is so thick I can't move without leaving a blanket of human odor. After a couple hunts the property would be significantly compromised for weeks, if not the rest of the season. And I see more deer from a stand because I'm above them. Otherwise I'm on top of them before I even see them. With the deer numbers, if I sit in a stand for more than 2hrs without deer, something is wrong. Stand hunting is just more effective for that situation, terrain, and objective.
Contrast that with where I grew up in southern Ohio. It's mountainous terrain with steep ridge lines and wide open hardwoods. Deer live in the green briar, laurel, and paw paw thickets on a shelf or head of a hollow. I set stands but rarely hunt one for more than a couple hours. I might hunt 3-4 stands per day, hunting my way between them. Other days I hunt ridges, zigzagging back & forth so I can hunt both sides of the hill at the same time. I look down to the shelves. There's so little undergrowth that I can cover a lot of ground without leaving much scent behind. And a lot of the terrain doesn't get used by deer so they wouldn't catch my ground scent, anyway. It's a completely different set of conditions than where I live in midTN, so I hunt it differently.
