I enjoy my Wii U thanks to the awesome first party content so far. I only owned one since last summer though. But if you're interested in Mario Kart 8, Smash Bros. 4, and 3D World, I'd say it's worth it!. You can get a refurbished one from Nintendo for only $225 that comes with Nintendo Land and 3D World.

And if you're bothered about the limited stock of GC - Wii U adapters, trying buying Mayflash's adapter that has 4 ports as well! Not only can I not detect any lag* but I can also use it for my PC emulators like Project 64 and Visual Boy Advance and various other PC games. It even supports rumble for some N64 games!

*disclaimer: I'm not a tournament level Smash player but I have played Smash bros since melee and am generally okay with the game.
However if you're a big batman fan, there's a PS4 sku with batman cover and the new batman game for 449$
