Please see the major Difference between here Compare Lightroom CC vs. versions 5 & 6 | Adobe Photoshop Lightroom CC history
In general Lightroom CC is Lightroom 6 with more feature and ability to Sync and edit images across all your Mobile devices.
Is there any new functions using Lr on the web/mobile and making edits from any device? why would I want to spend $10/mo. when I don't use or want PS?

Hope that helps
Thanks for the replies.
So mobile edits will sync to pc but not both pc and laptop correct?
At the moment a subscription makes it possible to sync via the creative cloud infrastructure, one desktop catalog But you can sync several iOS or Android devices.
