We will agree to disagree on "shot angles." Tree stands create more awkward shot angles than shooting from ground. I have got many more dead broadside shots from the ground, and at close distance...mostly pass through shots. More possibility of pure double lung shots from the ground as well, at least that has been my experience.
Some days, you can see more deer as well, depending on their movements, weather, etc.
They both have good and bad aspects, but I'll stay on the ground. I have close friends who came close to buying the farm from tree stands. No thank you.
