In the end, who won? Wii U or PS Vita?

[Sephiran]

For the future of both companies, Wii U led to some better legacy because it was the system Splatoon was first created on, which became a major franchise in Japan, which helped Nintendo take more market share in Japan afterwards. Also, Nintendo in the end got strong profit returns from a lot of games made for the Wii U like Mario Kart 8, BOTW, New Super Mario Bros U and a lot of other Wii U ports to Switch. PS Vita basically left no legacy for Sony and no game made for Vita got ported to a PS home console where it would sell huge numbers. Games made on the Wii U and ported to Switch would end up selling 100-200M copies on Switch, which is an enormous amount.
