Help Picking a Tablet

Hello,

I currently own a Galaxy Note 2, and would like to get a tablet to accompany this device for college (starting in the fall). I am already in Google's ecosystem, so I would love an Android tablet. But I need a tablet with a dockable keyboard that can get work done with no performance issues. Honestly, the Surface is a tempting choice, but I would hate to have to manage a Microsoft account on top of my Google account, as well as paying for separate apps on each platform. But I have yet to see an Android tablet that has the work prowess as the Surface (or any android device that can hold a candle to Surface's build quality).

Overall I'm looking for an Android tablet with a good keyboard and strong performance. All other features are secondary.

Any advice or recommendations are greatly appreciated.
