SpiderOak looks interesting. The biggest features for me missing from other "sync a folder to the cloud" type services are selective syncing on a machine-by-machine basis and generating public links for my files. These are the only two things keeping me away from iCloud Drive.

Spideroak does both of those things. They call those features "sync" and "share".

I have a "work" folder that is synced to my work laptop and desktop, but not my personal laptop.

I haven't used the "share" feature, but it exists and it says right at the top of the tab in the client that it's for making public links.
