It's a few years behind is true, but the gap keeps widening. DP Alt Mode isn't supported. M3 and M4 support might never happen. It doesn't seem like a viable long-term alternative to be honest.
But for me, the long term momentum of new platforms as they release doesn't matter - what IS supported is excellent (including the brilliant GPU driver).
My Mac Studio M1 Ultra runs Fedora Asahi Remix perfectly with full support and is exactly what I need. So those who are looking for a fast Apple Silicon system that can run Linux natively will save $$ and buy a used M1/M2 from Apple or otherwise.
