I've installed this update yesterday and I find it to be a big refinement for me. Start screen grouping is a huge new feature for me as it allows me to segregate metro/modern apps from tradition desktop apps. I also love the new feature of being able to use your desktop background as the backspash for the start screen as i think it makes the interface much less jarring.
Although the problem is I'm hardly the person to ask on things like this since on a daily basis I'm using Windows 7, XP, and OS X at work and Windows 8 or even Ubuntu at home if the mood strikes me. I know this makes me much more tolerant of UI changes than the average user who usually works on muscle memory.
