Creative Cloud File sync fail on external HDD. Google Drive as alternative?

I work off a laptop with limited storage (500gb). We have a 1TB creative cloud sync plan. So I want to sync files to a HDD that is constantly plugged in. I changed the destination folder of Creative Cloud Files in the preferences area and all files moved fine. But I've had a syncing issue since. Today Toshimanu from Adobe support advised me that 'Syncing files through external drive is not possible' (even though they could not provide a web page stating this)

So, time to look at alternatives. I was looking to see if anyone else used Google Drive / One Drive or Dropbox for management and sharing of creative files (namely AI, PS, PP, AE). Any benefits or limitations?
