My "good" radios are Yaesu, Icom and Kenwood. I have a cast off Baofeng that works Ok on 2m. My low power HF gear is Xiegu. G90 and X6100. The G90 works fine in the field. I just purchased the X6100 for some QRP ops. Still in the box.

A few years ago I dabbled in DMR. My TYT hand-held had a good open source firmware. It was fun until a malicious individual hacked the computer of the principal software maintainer. No more updates, so the radio is frozen in time with the last updates it will ever have.
