, you're missing the point: Nairo's Zelda is good
because Nairo is a good player. He could play Dedede and he'd make him seem top-tier viable.
Now that isn't to say that a character's viability is born and dies with the player's skill, but it is a decisive factor. Sheik is undeniably the best character in the game right now, but I sure as hell ain't winnin' tournaments with her. I'm not a good player. It isn't fair to say that my demonstration of Sheik is indicative of how she fares in the competitive meta.
Zelda is a bad character relative to most others. I'm sorry, but that's the truth of the matter. She may not be
bad, per se, in a vacuum, where you can say, "Frame 11 jab? Frame 10 grab? Yeah that's good in theory (because we have nothing to compare it to and therefore don't know the relative value of a frame)" - but compared to characters like Sheik, who can play the safest game in the world, or even Ganondorf, who's slow but gets good reward off of his reads, Zelda doesn't really have anything going for her.
Geez that was a run-on sentence...
To put it in simple terms: anything Zelda can do, somebody else can do better. That's okay, you can put the work in and get results with her. Nobody's stopping you. But she isn't competitively viable, and that's that.
