There pretty similar. One of the authors of the Robbins review book is actually the creator of the website. I liked webpath because it was on computer and the explanations were really short and sweet. In addition, he has really nice tutorials for alot of high yield topics. Also, he has lots of pics, CTs, MRIs, etc..
But, as far as the questions go they are pretty similar to questions on step 1 and to the questions in the Robbins review book. If you can do path questions in Robbins + webpath+ goljan, you should have no problem with path on the real thing.
