since unlimited is not always quite unlimited, i like to be independent of rclone's crypt. I am still using rclone to upload the data though.
In my opinion it is just a matter of time i have to switch to another unlimited cloud again. e.g. google bans "unlimited".
using encfs allows me to switch to any cloud I please, without having rclone to support it (yeah i know i could mount it locally via rclone, but where is the point).
Also rclone with 8 simultaneous transfer seems to hog quite some CPU resources, which encfs seems to handle them with way less resources.
rclone crypt is quite under construction, see issues/discussion on github. until this is finalized i feel safer using AES 256.
Why now? Since I have to migrate now, I may also change to crypto on the way.
