Nexus 10 is also great for flashing custom firmware. Keep in mind that Note 10.1 is worse than Nexus IMO, my friend owns one, the screen isn't that good and it runs slower, the only thing that would make me change to it would be the S-Pen. Now Note 10.1 on the other hand is quite good. But according to some video reviews I watched some time ago, it lagged very badly, so I wouldn't go for it because of Touchwiz.
If you want the best media consumption device, then Nexus 10 is really good go, the front facing speakers are amazing (take in consideration that I listen to 4h30-6h music on an average day basis [cellphone + tablet], and I don't mind listening to it using only the speakers instead of my headphones)! Also, battery is a beast, I can get 4h-5h screen on time with CM11 with moderate usage
For that price, and the qualities Nexus 10 is really a good go! If you want to check some other tablets as well, check this post:
