They're all identical keyboards -- AFAIK, literally -- so if you like it on one (or don't like it on one!), it'll apply to the rest. I have a 2020 MacBook Air and think it's one of the best laptop keyboards I've used in a long time. (And it makes me really hate going back to the butterfly keyboard on my work laptop, even though I found it okay to type on previously. I actually never had any dead keys on it, or on a previous work laptop with butterfly keys, or on a personal MBP 13" that the Air replaced.)
