Each type of tree stand will have their uses. Climbers are the best overall treestand in my opinion. You will bring it in and out of the woods each hunt. It will always be sitting at home ready to go hunting with you. No matter where you go hunting you will have the option of using a climbing treestand. I use climbers on all day hunts.
Ladder stands are my backyard tree stand. I use them behind the house and down the road on my brothers land. They are always set up and quiet to get in, great for short hunts like after work and the time and noise from setting up a climber might get counterproductive. I cannot sit in a ladder stand all day.
