I really like the idea of BTRFS and what it can do. For my recent system, build in end of 2023 (not a year ago) I really thought about and compared the systems, but end up using EXT4. Here some thoughts I had:
I want to use BTRFS as my main system FS, but I wasn’t sure which alternative FS to use (there are other contenders too), if I need the extra functionality, if its 100% stable for me on a non Fedora system and I also did not want to spent the time learning and experimenting with it, yet. But I will. And if other distributions I install or boot into would work well with BTRFS, if they are not on the newest Kernel yet.
