Like you said, different kinds of success will differ answers depending on the points they prioritize.
To me the Switch is the clear cut winner simply because the Wii in itself while a success was also short-lived in it's active effect and actually was detrimental for what would come with the WiiU/3DS.
The NES era however is I'd say the only real contender here, they had the Mindshare of a market they basically reborned themselves and a pop-culture revelancy.
Thing is, the medium was also still arguably in it's infancy so it couldn't capture the large public the VG space has knowadays. It's something Nintendo managed to capture it's essence during the Switch with an appealing product to all sorts of demographics that wouldn't alienate their core or casual audience for example. Then, you go into the stuff that's extras like the movies, theme parks and internet culture in general and Nintendo IP's remain strong in the minds of people, even from the younger upcoming generations.
The Switch is technically the equivalent of the NES success but in an era where the medium has matured and the competition widely more stiff than when they entered it first completely unchallenged
