What audio apps made it over? Audio is a gaping hole in Linux land. No drivers, no major support, no major DAW's, etc.. I can't move to linux primarily because of audio... not because of the other stuff you mentioned.
Agree to disagree partially. Bitwig is a major DAW, runs on Ubuntu. Native Instruments interfaces have their drivers in the kernel. YMMV with other DAWs/interfaces though.
This is why musicians are almost uniformly on macOS. I love Linux and I've been using it since 1998, but there's a lot of work to be done on the audio front for them to catch up to Apple.
