Pretty much spot on.
Both are incredibly shallow intellectually. One displays rather pronounced traits of sociopathy/personal ruthlessness; the other one appears to be genuinely a bit kinder. But neither has achieved much of any great substance. Ardern simply shouldn't be given all the credit that she's been receiving for her COVID response. Shutting down in March was the obvious and only sensible thing to do and she did that -- well done but that doesn't deserve endless praise. As soon as things became more complex (e.g. see current situation), the government's response has been increasingly shambolic.
This election will be a fight between the a government with reasonably competent "star turns" but a hopeless bench plus almost zero transformational ideas (Labour/Greens) versus the morally deplorable/senseless ideologues (National/Act), with the ever obnoxious NZF in the mix. The rest of the parties are irrelevant.
