This doesn't have to be an either or proposition.During primitive weapons season,I mostly hunt on the ground.It's hot,the cover is very thick being mostly hardwoods and the deer aren't as skittish.I like getting to my spot and set up w/the least amount of noise.When general firearms comes in,I go to my stand frequently.The leaves have mostly fallen,it's cooler and many hunters unknowingly push deer.On stand,I've had both hunter and deer pass under me never knowing I was there.Sharing a ground blind w/a friend,2 doe broke from a tree line about 65 yards away and came right at us.We ducked as one jumped over us and the second one put on the brakes and went directly around behind us.Take your pick!

Sometimes no option at all
 

Some have to retire from the parachute hunting regiment.

Actually in Maine, I'd seriously go with a ground blind, as it would give protection from icy cold winds. With hand warmers they might fit the bill.
In southern hunting, I'm afraid they might be a "hot house" on a warm September day.

Nothing I see is universal for every location.

Blinds for me..But Im all about stalking.. I feel the deer is playing the game with me, they hear me, I lost, if they dont, well then I won...

I've had a few nice hunts when I hunched down between a fork of an old fallen tree and cleared the l\leaves away. Got a two for one last year from behind a log. If you find the right log and are pretty certain where the deer are coming in from, all that is exposed is the top of your head and a purty blue barrel. I prefer being in a tree when bowhunting though.

I hunt in Kansas. I almost always sit in a stand although I use my blind alot for scouting to sit in a bunch of different spots so I can set up quick where ever I want that morning or evening.
