Support for the Rockchip RK3399-based boards seems pretty good. Audio and wireless on my NanoPi M4 have worked flawlessly for me. No problem playing YouTube videos, either, even at 1.5x speed. Editing 3D CAD files using Freecad in Debian 10 has also worked great.
The only things I miss are being able to run the latest versions of some software, which are often compiled only for x86 or MacOS. For instance, I'm currently stuck on Debian's Firefox ESR (currently Firefox 68.4) because Firefox doesn't offer precompiled binaries for AArch64 on Linux.
