[gentoo-user] Data corruption wise: Encfs or Ecryptfs ?

Hi,

since I lost some data due to a local power fail
on a encrypted directory I would like to ask,
what kind of encrypted directory (NOT partition)
on a ext4 filesystem may be easier to recover or
less prone to such kind of interrupts: Exryptfs or Encfs?

Are there additonal things to pay attention to
for choosing 'the right' way of encryption?

Thank you very much fo rany help in advance!

Best regards,
mcc
