The issues with both random-access performance and fsck times vary a lot
according to *exactly* which version of each you're using.  I'm in the same
group as many of the developers for both, and those guys are very busy.  Last I
heard, the fsck time and memory requirements were pretty similar between the
two, and any version of XFS with delayed logging should be pretty competitive
with ext4 for random access or metadata-heavy workloads.  I don't even know if
that information is current any more, though.  As always, YMMV and test your
own workload.
