I'd say it's closer to what 7 was to Vista, in terms of performance, but a step back in terms of UI usability. But I should note that I'm just a regular, non-power user, so I don't delve too deeply into things. One weird thing that I do quite enjoy, is the centred taskbar icons. Reminds me of the olden days when I used to use my housemates Mac.

Meh, tools that power users use are the same across Windows versions anyway. Wanna set up your network interface? Win7 interface. Wanna add a scheduled task? Some old windows iterface. The same goes for a lot more other tools like event log, disk manager, regedit, group policies manager, etc.
