Honestly, I'm not impressed, as it's about as it's just a straight up diff of some collected metrics from different snapshots with no real context or even mapping of events it diffs to the application/user/process responsible, and the discoverability of what actually changed isn't great.
The reports simply show as HTML text lists (all in red strangely, which I don't like), and unless I'm mistaken, there's no interactivity with them. I suppose it's a nice before and after, but it feels very limited in the information it offers, and I honestly don't like the UI presentation at all. Similarly, the documentation references UI elements that don't exist (for example, it mentions a Results item on the main menu that is not present, and I believe they mean Analyze).
Edit: added to last paragraph since I hit submit too soon.
