I'd say it's both... In particular 6.16 seems to be a defining point in terms of stability and performance at least for me. My RX 9070XT is finally running with no issues since 6.16 that I've noticed in any of the admittedly few games I play.

Mesa, the kernel drivers and Proton have all seen a lot of growth this past year combined with a bunch of garbage decisions MS has doubled down on... not to mention, enough Linux users in tech combined with Valve/Steam's efforts have made it visible enough that even normies are considering giving Linux a try.
