Fun fact though, on Linux you can force high-bitrate SBC on almost any headphone to get almost the same result as AptX.

SBC and aptX have the same quality (at the same bit rate). You are most likely talking about SBC XQ and aptX HD: http://soundexpert.org/articles/-/blogs/audio-quality-of-sbc... & https://habr.com/en/post/456182/

Indeed, however the AptX family has other codecs that support even better quality (AptX Lossless) and lower latency as well as adaptive bitrates, so modern AptX support is still better (hence almost as good)
