Just had the chance to work on a 16" for a bit, side to side with a 2018 butterfly 15" and my late 2013 13". I can imagine why some people liked the butterfly keyboard (when it works): it's extremely fast to type on, so much so it takes a bit of getting used to. It's like going from a typewriter to a laptop keyboard. The 2013 keyboard feelslikethat typewriter afterwards.
The 16" is really the best of both worlds. It's stiffer and has less travel, but it doesn't feel like typing on a wooden board. Very accurate. But, like any keyboard (particularly the shallow travel ones these days) ittakes some getting used to before you reach speed+precision.
