Have just looking at Lightroom cc (been using Classic / desktop version for many years). The interface looks great and very clean. Two key features which are missing (will prevent me from changing) are the ability to rename files and smart albums. The 'templated' renaming tools in Classic are great for bulk entering say date/time/locations. This is really the first step in my workflow. The second is the smart albums. These are the cornerstone of automatically having the "best of" albums for sharing. Whilst there are lots of other features not in the cc version, these are the basics amateur photographers like myself need.
