I have neither, but if and when I get one it will be a 4 post. I think they both have their advantages and disadvantages. My thought process and I may be wrong, is that a 4 post is a bit safer, and offers better/safer storage. As for buying one, I would approach like any tool, buy the biggest and best you can afford. I looked at Backyard Buddy a few times at Carlisle and they def were a quality product. At the time they were being made in the US.
