I'd love to say the same but on my Lenovo laptop I get frequent disconnects with bluetooth earphones on Linux alone. Apparently it's a firmware problem with the AX200 board, but even after having updated the firmware and following all the online fixes I still have the problem.

My whole use case for my laptop is getting away from my desk when I want to read something and listen to music at the end of the day, but it's annoying to have to reconnect the earphones every 10 or so minutes. Like everything Linux, it's incredible as long as you have supported hardware and you don't bump into some weird edge case.

I definitely love it for the "it just works" (or rather, you have full control to make it work) factor!

I'm not familiar with the latest in BT audio, but isn't the standard still sub-par in that it has very limited overall frequency bandwidth, resulting in deep sacrifices to fidelity?

I recall a detailed analysis of different BT audio codecs a while back, and the spectrum analysis always showed relatively high noise floor and frequency roll-off (hi-cut/low-cut) within the threshold of human hearing (though admittedly close to the limits). Also, I recall (and this could just be the 2016 tech I am familiar with) that overall bandwidth was limited in that if you played something with low frequency tones, the upper frequencies were dropped, or vice versa. I used to confirm this by using a flat EQ setting, then boosting any range, and you could easily detect the loss of frequency response in the adjacent or distant ranges.

Is this a thing of the past now?
