I would say ground blind but now that ticks are running more and more rampant I opt for the trees and prefer a climber over a chain on,,, BUT I find myself hunting out of the chain ons more than the climbers in the mornings so I don't make too much noise "going up"
I think I'm 40% deer harvested from the ground,, way better shot angle and honestly they can be as nervous as anything the thrill ride is you must let them get past you and once they are looking ahead the shot is yours and you MUST have the quietest clothes you can afford or ground hunting won't work.
