You have the last good one. My 2015 died and my employer gave me a 2017 that promptly died 3 months later. Apple Care and the genius bar were a pretty shitty customer service experience but I eventually got it back. The keyboard is worse than the rubber domes on the $200 Walmart Black friday special I got several years ago. That's not a joke. For the 2017 model Ram maxed out at 16gb which made it a laughing stock for that era. The touchpad is bigger and still good, but feels substantially worse than the 2015. After a year the battery life was a joke @ <50% brightness. It doesn't feel noticably faster than the 2015 either.
My 2015 was the best laptop I've ever used by a longshot. Thinkpads of the same era match it in build quality and have slightly better keyboards but the touchpad and the Mac workflow are something I grew to love.
The keyboard on the 2017 was so bad when a coworker with an old model was showing me how to do something on my laptop he genuinely thought it was broken.
I have a work provided 2019 13" Mac Book Pro. I was hesitant to let them replace my 2014 MBP because of all the negative press about the new keyboards. FWIW, I now prefer the 2019 keyboard over my personal 2014's MBP, the latter's keyboard now seems mushy and imprecise. So, aside from the touchbar, which I still don't love, I prefer the 2019 MBP over the older model.
That's what I've been saying as well to those who ask. The last good one. Even though it was the staingate one. Typing this on a banged up 2015 13inch. It's seen MacOS, Win for a year and now is on Kubuntu. Battery doesn't hold an hour, but I have yet to overcome the reluctance to pay for something not as good.
It might depend on your typing style. If you hit the keys with force, you might prefer rubber domes/mech keyboards, if you flow around the keyboard just gently tapping the keys, butterfly is amazing. I would easily pay $200 for a desktop keyboard that gives the same typing experience.
I'm fairly heavy handed so maybe that's why it doesn't appeal to me. I use Box Navy switches on one of my mechanical keyboards. Those are notoriously heavy.
Kailh might make something lighter than MX blues. Not sure what's out there on the light side. I'm sure cherry or someone must make something nice that still clicks. I also use linear switches around 60-70g.
Browns are lighter. Low profile Kailhs are even lighter. Right now I am using a scissor switch keyboard and I enjoy it a lot, but I am going to give kailh low profile browns a try. I like the general feeling of mech keyboards, but I don't like blues. I hope browns will be it. If not, scissor switch works well for me too, although my keyboard has issues with polling rate, sometimes when I type fast it swaps keys around.
