If you have somewhere else to play it, then, at least according to DF, you shouldn't go for WiiU version:
"With a visual standard that matches the PS3's in almost every area, the Wii U offers by no means the best way to play Watch Dogs. We're spared the heavy tearing of Sony's last-gen console but the v-synced playback on Nintendo's console comes at a high cost. As is the trend for many of the ports to Nintendo's platform, performance is a genuine issue. To an extent, having an off-TV play option for Watch Dogs is plus, in much the same way it is for most Wii U editions of last-gen games. However, it's clear the touchscreen aspect of Nintendo's controller is under-utilised. It's been an extra six month wait for Wii U owners, but this hasn't manifested in any kind of tangible boost, leaving us feeling somewhat disappointed."
