If the choice is between memory contention and all of the issues that come with btrfs, I think memory contention is the better option. That said, if the only issue is that ZFS's memory profile is too heavy for personal systems, that seems like something that justifies some tweaks to ZFS, possibly a "home use" operational mode, rather than a completely new FS, am I right? I'm using ZFS without incident, but my workstation has 64G, so not really a good example...
