Apple had a dark period between 2016 and 2019 when the keyboards on MacBooks were complete and utter garbage, but in 2019 they admitted their mistake and dropped the butterfly keyboard.
Both my work-issued 2019 16” and my personal 2023 16” have excellent keyboards.
Long 3 and a half years that I didn’t even feel at all because I’ve never even touched a butterfly keyboard MacBook. My previous personal MacBook was a mid-2015 15”.
No worse than most other laptops, now. A little better than many of them. Not as good as back when Macbook Pros were still thick enough to hold a disc drive and the keys had a lot more travel, but nothing like the dark days of the very-loud, shitty-feeling, unreliable Macbook keyboards of a few years ago. Totally OK.
(FWIW I use a mechanical keyboard with mine when at my desk, but I don't, like, hate life when I'm away from my desk and have to use the built-in keyboard, even if it's for a whole week. It's fine. I don't even really think about it.)
The new Mac keyboards are fine really, they rolled back from the problematic butterfly keyboards to the older magic keyboards (whatever that's actually called, but it feels a lot better and is a lot more robust) - thankfully I skipped the 'butterfly era' completely when I switched from a mid-2014 13" MBP to a 14" M1 MBP.
