I also have a 13" from 2018. No issues with it, keyboard works fine and used daily, having a shitty no name 40 Euro 9 USB port dongle, no errors, maybe 3 reboots in all this time. Love it for the portability and somehow like the keyboard. I also have a 16" at home, more powerful, love the screen on it, might seem weird, but I'm not sure which keyboard I like more at this point, I kind of got used with the butterfly. The only issue I had and it's a bit frustrating is with the sound since upgrading to Catalina, after a while it goes wild and connects and reconnects the sound device, especially with headphones.

As a long time user of a Dell XPS, I would never go back to that (poor bluetooth and WiFi support after 2-3 years, battery sucks after a while).
