Team collaboration : Synced files or Cloud Documents ?

Hello !

We're a team of 6 Concept Artists working remotely on collaborative projects. I'm looking for the optimal shared online storage solution for our creative files (paintings, sketches - mostly PSD, png, jpg, occasionnally a few After Effects and Video Files). Each artist should be able to access the works of others. This shared folder needs to be secured (we work on confidential projects), it should have file versioning (since you're never safe from file corruption or human error), support a complex folder hierarchy and it should be as straightforward to use as possible.

Up until now, we've been using Google Drive to do this (like a lot of creative teams, I think). It's great for file versioning and folder hierarchy, OK-ish for security - but it has its limitations in terms of user interface - and above all, it's not integrated with the Adobe Suite. It's for example impossible to preview Large PSDs whithout downloading them, and sometimes syncing while saving can lead to errors and even corrupted files.

With Adobe's recent efforts to promote Creative Cloud, moving to a comfortable 1TB of online storage space per user... I'm wondering. Is the Creative Cloud now robust enough for teams to share ALL their files on it, and to completely replace a separate cloud storage solution? And if so, how to go about it? I did a few tests and spent some time reading the available documentation, but I'm still struggling with whether we're supposed to use Cloud documents or Synced files.

• Synced files look a lot like Google Drive - it could allow us to share a precise folder structure containing our PSD files, with our exported JPG & PNG. But I'm worried with its limited features - especially with the impossibility of doing selective sync (see here).
  And overall it looks like the feature might not really be designed for true team collaboration (see here).
• Cloud documents look like the "new big thing" featured by Adobe in terms of collaboration. I love the photoshop integration, the online preview, the comment feature... bu
  • It seems impossible to save anything other than the "PSDC" format as Cloud Document. JPG and PNGs are too important a part of our workflow.
  • I don't see how we could use it to share a full folder hierarchy ? Sharing individual Cloud documents looks easy, but how could we do the same with folders containing cloud documents ?

Any advice, or feedback from existing creative teams, would be very appreciated!

Do you use Synced files ? Cloud documents ? A combination of both ?

Thanks for your help!
