Is there something unique about the hardware that causes this?
It really shouldn't happen - that's what the journal in both xfs and ext4
is for - to replay after a power failure and keep metadata consistent.
What kind of corruption are you seeing?
Generally if a power loss causes filesystem corruption on either xfs or
ext4, it's due to a storage problem. (Unless by corruption you mean
lost buffered IOs, which is really an application issue.)

Can you expand on this? What kind of repairs are you talking about?
Generally xfs_repair is at least as fast as e2fsck.
