What was then always answered to that question is that XFS and EXT crashed very often at random at that time, and that you had much easier data loss with XFS and EXT than with ZFS on FreeBSD during power cuts.
That's true, but a random Quora discussion does not make ZFS the "default recommended" filesystem.
I think ZFS has been the default choice for the FreeBSD installer for quite some time now. It is correct to say that ZFS is now the default.
I just checked on FreeBSD 13.0. Both UFS and ZFS are offered as options by the installer. There is no "default." It would be incorrect to call something a default where it is not a default. It has been this way for some time now.
There are also the performance differences which can sometimes be significant depending on the workload. In general tests, ZFS is often faster than UFS in more areas.
ZFS can certainly be faster where there are memory and CPU resources available. However, ZFS has (had?) trouble working in the sub-1G RAM department; maybe this is no longer the case, perhaps @Patrick M. Hausen is familiar with the current state here. For those of us who run services on small virtual machines (128MB, 256MB) ZFS is simply not viable.
