I am currently using it now. I can't compare it to the real test, but I feel that a lot of the PAT is just practicing. For instance, I feel like cube counting is just knowing how many sides are open based on quickly looking at it instead of actually counting each side, and that just comes with practice. the software comes with three generators (i forget for which subsections), and it never expires (which you may or may not care about depending on how far out your test is). I think some people say it's easier than the real test, but that just means you should make sure you get above the score you are aiming for on the software.
