I think the guy is forgetting that all the system is packed in a portable console. Lol. If it was a proper console, I would totally agree with him, but it is not. Try holding a PS4 in your hand to play. Lol.
Plus, I am sure there is more performance yet to be unlocked over time as developers get used to it, in addition to that, when a game is built from ground up for a system, you will likely get more out of it.
To be honest sure I would have preferred Nintendo release a proper console that is somewhere between a PS4 and PS4 Pro in performance for that price. But my minimum expectation was Wii U performance due to the form factor, and it is definitely faster than an Wii U, so I am happy
I think Mario will probably manage to hit 1080p when docked.
