I would strongly lean away from XFS. JFS appears to be the safest bet 
and its performance is actually very good on all aspects from benchmarks 
I have seen.

reiser4 is having all sorts of issues getting into the kernel and XFS is 
having all sorts of issues being maintained. Some kernel developers even 
went so far as to say that they do not want to have anything to do with XFS.

XFS is good until you lose power while the disk subsystem is under load. 
This was when XFS was in its best form too (around 2.4.18 - 2.4.22). Not 
many people use JFS but it does actually seem to have the best environment.
