I prefer handheld consoles to home consoles so my answer is obvious, PS Vita!

But I also like playing games so I choose the 3DS.

It'd be really hard for me to pick, but currently I spend more time on the 3DS since I am focused on games from there (Animal Crossing/ Tomodachi Life/ Bravely Default) I do have a lot of Wii U games to get through too, but due to my schedule, I am only able to focus on so many things atm.

Okay, I laughed. Brutal burn... 

Wii U. I like its library of games more than 3DS's, and I prefer home consoles overall.

I haven't touched my 3ds after getting a Wii U and I have more or less been exlusive handheld for the last 10 years :/

Only a new advance wars would get me excited to play the 3ds now..

WiiU wins, because its library of games is better! Plain and simple, in the past year or so I've barely touched my 3DS due to being busy with the WiiU!

If Wii U gets Animal Crossing and Pokemon then it wins, until then I go 3DS.

Wii U, its my all time fave system and im more home console oriented, 3DS is superb though.

I'm going to hold off on voting until I actually get some quality time with my 3DS, but at this stage it seems incredibly unlikely it will top the Wii U. I prefer home consoles, and the kind of games that come with them.
