My MBP started having occasional errors where some letters would be repeated or come out of order. As someone who writes for a living it was incredibly frustrating until I tried another computer and realized it wasn't me--it was the keyboard. Long story short, I took it into Apple and they put a new top case in my MBP (2018 touchbar). In the mean time I wrote on the 12.9 iPad pro some (the smart keyboard is much more productive than I would have thought once you get used to it) and I tried a 2015 MBP for a few weeks.
I have to say after using the 2015 for a few weeks and coming back to my (fixed) 2018 MBP I really prefer the newer butterfly keyboard. While I'm nervous about reliabilty, for me the 3rd generation butterfly keyboard has a much better feel and the sound is less annoying than the higher-pictured sound of the keys on the 2015. Plus typing on the 2015 was tiring compared to the 2018--that's the only way I know to describe it. I feel like I can easily type on the 2018 with a light touch but the 2015 did not feel that way. The mushy feel and longer travel were frustrating.
It probably helps that I've been on the butterfly keyboard since 2016. When I got the 2016 it took me about two full months to completely acclimate to the lower travel. I had since had a 2016 MBP, a 2017 MBP, and then a 2018 MBP. Interestingly the 2018 is the only one I've had keyboard problems with, but it's typing feel is definitely better than the 2016 and 2017 keyboards.
After reading others experiences, I thought I'd prefer going back to the 2015, but now that I've done them back to back I really prefer the 2018. I frequently write 6+ hours a day and it's just more comfortable. With that said, I do hope Apple can solve the reliability problem. With the current failures people have experienced I'd be nervous if my MBP was out of warranty. When I picked up my MBP with the replaced keyboard, the apple tech said he hasn't seen any of the ones who got a new keyboard come back. I hope he's right, but of course his opinion is not a solid assessment. The tech who requested the replacement seemed to acknowledge they have had higher than normal keyboard issues with the newer design.
Apple clearly has some quality issues with these keyboards, but I have to say trying the 2015 and coming back to my fixed 2018 made me sold on the new design though not convinced Apple has it at the quality level it should be. I would like to see the four year warranty on the 2018 model however. I bet it will come as these machines get around a year old.
