Unlike Dave, my studio actually uses Ae CC 2018, so I can speak to it from experience. I’d consider it a big step up over Ae CC 2015.
One big caveat, though: the latest version drops support for legacy QuickTime codecs. Most common production codecs are now supported directly by the Adobe apps, but if you’re using an older codec, you should stay on the previous release and consider re-evaluating your workflow going forward:

(A little backstory if you’re curious why QuickTime support is going away: https://forums.creativecow.net/thread/2/1129010#1129012)
Ae CC 2018 should read Ae CC 2015 files without issue. (But this should have been your experience going from CS6 to CC 2015, too. I’d be curious to hear about what kinds of issues you rant into.) Note that you can install multiple versions of Ae side-by-side, so you can test for yourself how well it work by using the Advanced Options in the Creative Cloud installer, and unchecking “Remove old versions:”
