It all depends on the area you hunt. The places I hunt, there are natural elevations and natural cover that I can hide in. I prefer the ground more because I like to move. I'll sit still all morning. Mid-afternoon, I'll stalk. Late afternoon I'll sit again at a different spot. The areas that I hunt are more pressured so the deer tends to shift patterns every once in a while so I adjust. I have a spot, a backup spot, a backup to my backup spot and a backup to my backup to my backup spot, etc. A climber (I hunt public lands) is just too much of a hassle to go up and down the tree repeatedly. I use the climber only if I am hunting a spot where there is no natural cover or I can't get a clear shooting lane. You have to know the layout of the land, the behavior of the deer and adjust accordingly.
