RE: which is most important?
It all depends on your personal hunting situation...which you didn't elaborate on. I don't have a range finder but I would like to get one. I do have a tree stand and love it. I can always step off the distance to the shooting spots and get a good idea on the range. I can't get up off th ground without the climber. I don't like hangon stands so I would never use one. You don't have to spend $300 for a climber. I bought one two years ago for only $100 and it is a wonderful large stand.
