At this point they both have a large playable library, the 3DS has much to offer and the WiiU does now too thanks to more eShop exclusives and virtual console releases.
This isn't really a debate about "the wiiu only has nintendo games so that isn't allow to be ur main console", this is about which one you use the most for gaming!
As for myself the WiiU has become my main console for games right now. The 3ds is a little slow right now and thanks to Mario kart and Smash, hyrule warriors and 3D world i tend to go for it more. Also have been doing Wii Fit cause my bro found the bundle again.
