As for JFS its been a long time since I tested it but I had the reverse issue.
Oh and I know the issue you ran into with xfs its rare but has been known to happen I've hit it once my self on a laptop its a journal problem, and fsck isn't the tool to use.
There is a specific xfs repair tool to fix the journal or can rebuild it from the backup inodes

This might be true, but it's not the case for all. I've experienced very bad
corruptions on xfs myself, resulting in lots of non-accessible fake
files (random size, attributes etc) with random filenames including
non-printable characters - and there was no way to remove them, fsck
refused to fix them, too. Filesystem was in total mess and producing
various errors - it's fortunate that I was able to copy all real data
without corruption from it, though. Since then I try not to approach xfs
without serious reason.
I'd rather use JFS for huge filesystem which I've been using for many
years until ext4 appeared.. But for fs >16 Tb jfs is still best option,
I believe (far more stable in my experience compared to xfs, though
might be not as fast).
For several reasons most people don't consider JFS but I used it on tons
of servers for filesystems > 1 Tb (ext3 was a bad choice for huge
filesystems for various reasons) and never had a single issue with it.
At most, after multiple power failures during heavy write access I had
errors which remounted it into R/O mode and fsck always fixed it.

I don't really understand your implication: xfs is slower *due* to xattr
support? So if I will mount ext4 with user_xattr option, NFS4 from it
will become slower? How come?
