All I can give is my opinion on each bundle.
Deluxe Nintendoland Bundle
Pros:
-Best value for the Wii U currently. It was being sold on the Nintendo Store for $200.
-Comes with a physical copy of Nintendoland. It's a decently fun game but you can buy the game alone pretty cheap nowadays.
Cons:
-It's refurbised. I don't really trust refurbised items, although I will say I bought refurbised items from them & had my game pad refurbised. All have worked fine for the past year.
-Currently out of stock. May come back in stock. In my opinion it's worth the wait given the value.
LOZ WW Bundle
Pros:
-Comes with the LE LOZ gamepad which is pretty awesome.
Cons:
-Unfortunately, this is the only bundle that does not come with a physical game. Instead you get a code to download WW & another code to download the Hyrule Historia book.
-Will probably be hard to find by the time you plan on buying it, as it's already becoming hard to find anywhere but gamestop.
Super Mario Bros. U Bundle
Pros:
-This bundle is the only way to get both SMBU & Super Luigi U on one physical disc, potentially making the disc more valuable in the future.
-You get two games in one bundle, always nice.
-Sometimes this one pops up for around $250 on ebay.
Cons:
-Nothing I can think of.
Mario Kart 8 Bundle
Pros:
-Best bundle for value if & only if you don't have a wii-mote.
-Comes with a physical copy of the game.
-Comes with a special edition wheel (only available in this bundle) & wii-mote.
Cons:
-It's hard to find right now, & there are rumors going around that it is a limited bundle. May not be restocked, so you may not find it by the time you're looking for it.
-$30 extra for the limited edition wheel, & wii-mote. A good value when you think about regular price, not so much when you figure in other deals if you don't care about LE items. The Nintendo store sells refurbished wii motes with nunchuks for around $30 (shipping included).
Personally, I bought the LOZ bundle. I love the gamepad, but I'm a huge zelda fan, & I always figure if I'm gonna drop a bunch of money on a system I might as well get one that's worth the price. Not so sure this was since I do not care for downloadable games. If that doesn't matter to you, go for it if you can find it during the holiday deal season. It will probably be on sale along with the NSMB bundle.
Personally if I had the choice today, I would buy the MK8 bundle & sell the gamepad to buy the LOZ one. That's just because I like LE stuff though. Hope this helps.
