My 10 year old Dell XPS M1330 with Intel Core 2 Duo T8100 and 4 GB RAM with original HDD still running strong, had 11.2 installed on it. I just finished updating it to 12.0 release without any issues. I have only good things to say. I use Xfce. The filesystem is ZFS.
A while back, I took a snapshot of /root and installed Gnome 3. It was too big for my laptop. I rolled back. The snapshot and rollback were amazingly fast.
I find FreeBSD more cohesive. I have not tried it on modern devices, but my experience with it on my decade old laptop and VMs is extremely positive.
A similar cohesiveness is achieved only when I handcraft my Arch. Maybe, it is just the feeling.
