Most likely Nintendo, how much depends on their next gen strategy.
MSony will probably be around 8x PS4, so some 15TFLOPS - unless they wait a bit longer so they can have native 4K rendering or something really unexpected happens and we have mature 7nm much earlier.
If Nintendo tries to make something that will be able to run 3rd party AAA titles @1080p, some 5-6 TFLOPS should be expected and that would be massive jump from WiiU.
EDIT: I haven't seen handhelds are option too - then there is no doubt, 3DS is so weak, any decent modern SoC they pick for next handheld will be humongous jump.
