Like I said, if you search hard enough you can find someone that says something different, but most reviews say the Apple keyboard is either the best, or among the best for a laptop keyboard.
You question the legitimacy of reviews that say the keyboard is good but then you mention one that says it's bad. Why aren't you questioning the legitimacy of that review? I mean you can't just question the ones you disagree with. Well you can but it seems silly. I don't think there's some big conspiracy where reviewers are saying the keyboard is good or bad. I think it's just some people like it and others don't.
I've followed Lisa's channel for many years now and her detailed reviews have always come across as incredibly impartial -- a sentiment I think most agree with. They match up with my own experience when I try the reviewed item. She discusses the key travel and overall feel in a way that I think is extremely accurate. It's helpful for those who can't try before they buy.
But really... The new MBs have "the best or one of the best" laptop keyboards? It's servicable and you get used to it, but is it even better than average? There's nothing notable about it other than its very low travel. Lenovo, HP, Dell all seem to have keyboards at least as good in some of their laptops.
Seriously you don't need a review to tell you if it's good for you. A review is good as a baseline but if you physically touched the keyboard and feel like it's terrible, then it's terrible. I can't argue with that because it's what you need and want, and maybe it's not that. This is why everyone likes different things. I can think something is great and you can think it's terrible and we're both right. Believe it or not, some people absolutely loved the butterfly keyboard. I can't comment on it because I've never had a laptop with one, but some people swear that it's the best keyboard they've ever used in their life.
It's fine that some liked it -- but exceptions don't make for great buying advice (especially first-gen butterfly). Most seemed to find it anywhere from acceptable to shallow, dull, loud, and unreliable.
But then what we're really saying is that there can't even be a "best keyboard" since there's no way to measure such a thing... which is true, but trivial.
Oddly enough, my favorite desktop keyboard is one that probably very few people would really like, but I would describe it as an "acquired taste / not for everybody".
