Jiggs is still underrated, I said this before and I'll say this again. If nothing else, Jiggs can plank like a King (queen?). She is better then Zelda.
Ultimately, Zelda is not forced to approach as often as people believe, a lot of projectiles are invalidated in terms of forcing approaches by consistent powershielding (which the community needs to get better at), and her defensive game is very powerful. So does have ways to actually threaten people in shield too (due to her smash lasting forever and shield-poking) and the first few frames of her grab being almost indistinguishable from her dash attack.
That said, what it matters in is MUs, and Zelda has at least two surprisingly good high tier MUs, which is certainly far more then anyone around her can say. Namely, DDD and ICs. ICs in fact, is almost an even MU.
But... for all the influence she has on the current metagame, she might as well be bottom 5, nobody actually uses her, so in spite of the fact that she's better, she gets 0 results.
