That sounds good, it really is upto you and based on what makes you excited playing games. The wii u has an amazing library of games as well as the vita and modding them are a piece of cake.

The series S is an amazingly small console although all your modern games would need to be digital, and you’d find more value in game pass + emulating in retail mode (I think the dolphin emulator has also just started being ported over to retail mode).

Like I said, both choices are amazing and you just have to choose which makes you happier.
