Wow, that is quite excessive levels of hate toward the system that laid down the groundwork for all 3D platforming games thereafter. The analogue stick was quite a gaming revolution, albeit not the first place to implement such control mechanisms (looking at you p.c.). I am not attempting to tell you that your views on the N64 are wrong, but please lend me your ear for a moment.
There were quite a few gems on the N64: Super Mario 64, Banjo Kazooie, Diddy Kong Racing, Mario Kart 64, Super Smash Bros., and F- Zero X to name just a few that come to mind. Granted, the controller was pretty awful, but, come on, it isn't anywhere in the vicinity of terribleness as the original Wiimote & Nunchuk. Merely thinking back to my early days with the Wii gives me shivers down my spine at the horrendously dodgy motion controls. At least Nintendo eventually mollified the design shortcomings of the Wiimote with the Wii Motion Plus enabled controllers several years later.
But regardless, back to the N64. The system certainly was revolutionary, but it is by no means the "best video game console of all time". Anyone who truly believes that must be delusional. The Ps2, Gamecube, SNES, Dreamcast, Genesis, Xbox 360, and Ps4 are all far superior in my humble opinion. I do believe that Diddy Kong Racing is by far the best single player campaign in a racing game to date (dare I say even better than Forza Horizon 3). The same goes for Mario Kart 64 and its incredible Battle mode.
While I wouldn't say everything made by Nintendo since the N64 was a "step down", I would have to concede everything from the Gamecube and on was most assuredly an objective step down in quality. The Wii U was a step up from the abysmal Wii, of course, but not by enough, if you ask me. Obviously the Wii was better for soccer moms, and the like, but I am talking about the gamers who actually care about quality titles, not merely waving their arms in the air like they just don't care.
Keep in mind, the following graph is merely my own opinion:
