For me it's probably Shantae and the Pirate's Curse. I could have picked Smash Bros. 3D easily, but I enjoyed Shantae a lot more - even if it's an eShop game.

I could hug you.I dislike the God of War games and I don't like how Kratos is often considered Sony's mascot. What about Sackboy? :P
What I really disliked was the story. Basically Kratos kills everyone and screams, "You lied to me! You betrayed me!" and ... he gets fooled into killing his family by the gods or something. Boo hoo. He should've been more attentive.
Sorry to anyone who thinks this post was a little harsh.
You can only transfer all the games. The system transfer basically moves everything to the new 3DS (you'll have to put the old SD card in the new 3DS as well). So you can't only transfer a few games. :o
You don't need any special equipment, just the two 3DSes for the transfer and internet access.
I don't know about the Wii U, sorry.
Donkey Kong Country Returns 3D is a full $40 game, so it's the most 're-compensating' reward. The game seems to play better on handhelds. It's 17, 660 blocks though, so make sure you have enough space on your 3DS if you select it.
If not, then I'd recommend Mario vs Donkey Kong - though this year none of the rewards were really all that.
