Hey,
I don't know what the regular qbank is like, but qbank plus has 2 extra mini qbanks. One is integrated vignettes, with several questions per vignette. I only did maybe 30-40 of these, and thought they were way easier than the actual qbank. I haven't used them since. There is also a physiology qbank, which I haven't used too much. There is also a diagnostic test, and another simulated exam. I'm not sure if these things are already in the regular qbank or not. Honestly, I only got qbank plus because they gave us a deal where it was only slightly more than regular qbank. Otherwise, I wouldn't have spent the extra money. Hope that helps.
