I have a Wii U ( no 3Ds ) n i can say Wii U is better

I think online play for the wiiu is a lot more fun but the titles on the 3ds is STAGGERING so rn I'd go with the 3ds

depends on what you want to play in my honest opinion. pokemon on 3ds is the way to go for me and the fire emblems seals the deal for it! the wii u is neat for emulation (nes, snes, gb gba, sega genesis, n64 & gc) with few games like wind waker hd & twilight princess.
