Surface RT VS Nexus 10

Only since my brother had got the nexus 7, i have been wanting tablet as we both somewhat share it. I have been looking for 10 inch tablets and its between the Surface RT and the Nexus 10. Which is better and why? I have a HTC Sensation XE and its getting old and im getting HTC one google edition, so its more like a nexus experience. But the the surface RT might be better for getting stuff done or as a good media consuming device.

Thanks
