XFS on my server VMs and my laptops and desktops.
ZFS on my file server. I’d use it on my laptops and desktops too (and have done when I was using Xubuntu) but I’ve switched toFedora which doesn’t come with a way to easily install with ZFS and I don’t feel like jumping through hoops to get it done. And I can’t stand btrfs. I don’t know what it is about it, but I just don’t like it.
I’ve always been happiest with xfce4-terminal, though I’m using Konsole currently until XFCE fully supports Wayland.
Way back when, I was more than happy with rxvt.
