I didn't upgrade my 2014 MBP but instead am using a Dell Latitude. Linux desktop very nice except the machine reboots whenever I close the lid. Sound works, video works (!). Zoom has an excellent conference call app.

Aside from the reboot problem, I'm happy Linux at least comes with up-to-date tools. Apple's GPLv3 phobia meant I had to continually install Brew and Continuum (Python3) to have modern tools.
