Assassins Creed 3 or Black Ops 2?

Which one is better for Wii U? Assassins Creed 3 or Black Ops 2? Which is more fun to play? I'm thinking about getting one more Wii U game.

I'm enjoying AC3 more on WiiU. I originally played it for a couple of hours on ps3 and was annoyed by the controlls and bugs. For some reason the wiiu version is easier to ply and hs far less bugs. Ive played for 3 hours and havent run into 1, which wsnt the case with the ps3 version where I hit 3 gme freezing bugs and 2 game breaking glitches during those 2 hours of playtime.
