These are two quite different apps targeted for different users. Lightroom Classic CC is intended for use on computers or laptops. Lightroom CC is intended for use on mobile platforms such as cellphones and tablets. You are comparing apples to musk oxen.
Let's have a show of hands: Among all Adobe Lightroom users, how many are using Lightroom CC, and how many are using Lightroom CC Classic?
By the way, for me: Classic.
I use Classic for my main stuff from the cameras and use the "new" CC for my cell phone "ONLY". Wife does the same. with hers. We don't feel that we have the same abilities within the new cc as we do the "Classic".
