[opensuse] What is your favorite Dropbox replacement?

Hi all, Probably many of you got a warning from Dropbox that from this November it will only support ext4 filesystems (from the linux world). Unfortunately my two most used computers  have XFS filesystem, so I am in a bit trouble. Before moving - to my regret - to something other cloud storage, I would like to ask your opininon: how do you manage this question. Google drive would be an obvious choice, but I still do not know of a decent linux client. Albert
