I did't have UW but I used kaplan for step1, and I'm using steps123 for step 2 now. so I can't really compare, but judging it fairly based on my experience of using it in the past 2 weeks, I have to say that the questions are very very well written and has been helping me to look at things in a different way and putting things together, the way that boards like to test you. The way it asks questions is difinitely better written and more accurate than kaplan, by far. What I also like about it is that, since Elsivier is also a publisher of many review books, after every explanation, it has excerpts from the books that it carries that pertain to that question, so it saves you time from looking for it in your review books, especially if you don't have those books to begin with. I wish I would have used it for step 1 insteakd of Kaplan, assuming the focus and the style of Elsevier's qbanks are the same for step 1 and 2.
There is a downside to it, I've noticed some tech cliches, maybe because it's a new product, and it was mostly the picture that comes with the question(btw, very good pictures). Sometimes the picture will not show up, and the question asks you to look at the picture but no picture is loaded. Or a few questions askd me to look at the pictures and the pictures shown had nothing to do with the questions, like "look at this chest xray" and I see budding fungus. So somehow some questions are incorrectly linked to questions. This has only happened about 6 times out of 700 questions i've taken so far.
