They are all pretty similar, but they do have some important differences. The 2 most obvious differences are the user interface, which I feel Data Tree by far has the best out of the three, it looks much more modern than the other two. Second is how and what data they collect, each one collects and organizes over a hundred different pieces of data on every property. None are better than the other, but Data Tree seems to have the most relevant information for us dealing with houses, where as Real Quest has data more relevant to people flipping land.
