I have the first generation TouchBar MacBook Pro. And I've gotten the bottom part replaced twice: once because I spilled coffee on my desk and my MacBook decided to drink it, and the second time because they didn't attach the bottom plate properly (they forgot 2 screws and 1 other just fell out).

The keyboard they replaced it with is significantly better. It feels softer to the touch, and it's quieter. The keys don't get stuck anymore and it generally feels like a proper nice keyboard.

That said. I rarely use the laptop in an opened-up state anyway. I tend to connect it to a screen + keyboard + mouse and enjoy the computer without that idiotic TouchBar.

Last I checked you can send your MBP back to Apple and they'll replace the faulty keyboard. I did it during a vacation, it only took them 1 week to send the fixed system back.
