Away from Android for phones? Highly unlikely. But for tablets? No contest. I've been using the latest Windows builds out of Microsoft since around February, on tablets, laptops, desktops, all-in-ones, and docked solutions. The approach to multitasking and productivity on Windows 8 tablets and larger touchscreens lets me be far more productive and efficient than on Android tablets. Furthermore, I feel like the Android user interface style on tablets (both the honeycomb-like interface and the Nexus 7 and Nexus 10 interface) is just a bit 'off'. The interface in Windows 8 perfectly complements Windows 8 (Metro) applications, and the way that such applications react to available screen width and height provides for a much more responsive user experience.

Every time I try to justify productivity on Android devices, it doesn't quite happen -- especially for document creation and editing. I've used most of the Office-style apps on Android, and I've used most of the sharing methods (Dropbox, Docs, etc.) as well. I'm a big fan of Google Drive, but in the end, Office 2013 and the sharing capabilities of the Charms bar offer a much more seamless and effortless experience.
As for efficiency, Android has done well. The 4.1+ approach to multitasking is great; it's very similar to Windows 8's multitasking, with subtle differences. The lifecycle of Android applications, when handled well by developers, allows applications to react well to being in the background. One significant difference is the approach to lock screens. Windows 8 doesn't let you launch anything directly from the lock screen, while Android doesn't have the same capabilities for displaying information on the lock screen (with the exception of lock screen widgets coming with 4.2).
Finally, in the aspect of responsive design, I just don't see what I want to see on Android tablets. Windows 8's Live Tiles work beautifully -- Microsoft did with Live Tiles what Android has been trying to do with homescreen widgets for years, save the interactive elements (i.e. play/pause/next buttons for music control). Snapping two Windows 8 applications on screen allows for multiple-app interaction without loss of efficiency or content.
I frequently snap Weather or Music in a thin window on the left of the screen, while having the Mail app or the traditional Desktop open in a large, right-side window. The applications adapt to the screen real estate available to them, re-composing lists and content not only to fit
the new dimensions, but to fit the new dimensions well
. The closest thing to this built into Android is Fragments
Simply put, navigating and using a Windows 8 tablet feels more natural and immersive than any of the Android tablets I've used. Android is more or less on par with Windows 8 for media consumption -- web browsing, music, images/photos, and sometimes video -- but beyond that, there's work to be done.
Edit: I tried to keep this short....
