Ask HN: Dropbox/Drive Alternatives?

Is there a great alternative for Dropbox / Google Drive?

I know this comes up frequently, but I'm hoping there's something new that I just haven't found out about yet.

For the record, I love the old Dropbox, where it felt native to the operating system and just synced files. But they keep adding things.

Google Drive is just maddening experience of figuring out permissions and and where my storage is being eaten up. I get 30g free though, that's hard to beat.
