Gotta go with Shadow here, I had TSPP twice, because I love the Simpsons show, but just never got into the game, and I really tried, the Shadow is just pure awesome, a players game, you score big on that, you really accomplished something, it is easy to understand, looks awesome, plays FAST.. not a game you are going to master in a few days, of course TSPP is not one you master in a few days either..
But again, I would go with Shadow, but not at 4K unless it is just flat out MINT.
