I’m on Windows and for legacy reasons also use ALAC. I started back in 2013 to convert some of my CDs for my car and phone, and realized quickly that to get the most of it, I’d have to streamline tagging and I only ever wanted to do this once. So I decided on lossless format ALAC, because I started with iTunes. That way, I’d have 1:1 bit-perfect copies of the music. I still use iTunes to “curate” the music.
When I buy digital downloads (or rip CDs, now mostly with EAC, since I have noticed that iTunes is a terribly unreliable ripper) I convert them to ALAC as well.
A couple of years ago, I considered converting my collection to FLAC, since that’s more native to Windows and Android, but I found since all my devices, and my home stereo play ALAC anyway, so I couldn’t think of any practical advantages to switch formats, so I still use ALAC. As you said, for all intents and purposes, the two formats are basically just the same anyway, just one is more Apple, one is more Windows/Linux. 🙂
