I have the previous generation hardware design as my personal laptop and a late-2019 macbook pro for work and I really don't hate the new one. I know some people have had some issues with keys getting stuck and what not, but I've actually had a pretty good experience with mine. I touch-type and I can type just fine on the newer keyboards. I would have liked to have a physical escape key, but besides that it's fine. I'm happy with the thinner and lighter design. The options of core i9 + 32GB of ram alone is worth getting one of the newer ones over a 2015 model.
Same, I own a 2014 15" and have a 2018 15" from work. I haven't had any keys break on the 2018 (yet...) and actually prefer the key travel on it to the 2014. The smaller size is an improvement and the dongle situation isn't a problem for my use cases. Not a fan of the keyboard layout and TouchBar, though.
If Apple let me spec a physical ESC key, inverted-T arrow keys, and native 1920x1200 point screen size @2x on the existing form factor I'd be VERY happy. Assuming, of course, the keyboard is actually reliable.
Ditto situation here. My work MacBook has been working great as well - the inability to charge my iPhone without a dongle has been frustrating but hopefully Apple switches out of lightning soon.
As for the ESC key, I rebound my Caps Lock key to Esc & Ctrl. Works great!
