At first I also started to use AE as I'm really good in grading photos with ACR. As you can grade only one frame I did it with Adobe Bridge (it was easier to browse through sequence looking for better frame). Then I applied this grading to all files and opened it with AE. Basic editing and export to PP. Slow, painful, awful workflow. The ONLY advantage - my beloved ACR.
Nevertheless, I'm really happy that I've spent time to learn how to grade in Resolve. The workflow and speed is perfect!
