My thoughts on the Wii U version: It actually doesn't look bad when you consider that this is running on a Wii U. In fact, I would go as far as saying that having something of this scope on the U is quite impressive. However, the framerate does look quite bad. Not anywhere near Just Cause 3 console levels of bad to where it's almost unplayable, but still pretty damn rough. But, as somebody else mentioned earlier in the thread, look at GTA V on last gen. Performance was comparable to this, but the game was massive for the hardware it was on so it was understandable. Same case here. However, the problem with this version is that a better version is releasing alongside it, a version with stable performance and cleaner visuals. The problem with the Switch version is that if you don't mind the (notable) technical issues in the Wii U version, and nothing else coming to the Switch in the near future interests you, then there isn't much reason to buy the Switch version (let alone the Switch), unless you just want the new hardware day one.
Personally, as a Wii U owner? I'm going Switch, but not for Zelda. I like the Switch itself, and having what will probably end up being the best game to hit the Wii U but better and portable is icing on the cake (very sweet icing, mind you). Also, I generally just don't like using the Wii U due to how clunky and sluggish it feels.
