Okay, let me take a stab at this, FWIW. As a full fledged editor, Premiere and Avid are better. But that better really shows itself when working with lots of footage. Then their advantages in terms of using the keyboard only, managing bins, metadata, adding specific markers on the fly, adjusting clip gain, handling of audio effects and stopping video and audio playback at the same time (Resolve actually continues playing audio on the Edit Page for another six frames after video has stopped playing--super annoying when trying to cut to audio) really start to shine.
But for even moderately sized projects, Resolve is plenty capable.
And I certainly wouldn't waste the money on Premiere for such work. esp. since you need an active subscription to open your projects.I also have Adobe Creative Cloud and Avid Media Composer. So I can use whatever I want. The last thing I cut on Resolve had only three color corrected clips. Would it have gone more smoothly in Avid or even Premiere? Yes, but Resolve is getting more and more capable with every release. So I'm willing to work it hard, see where it breaks and communicate that back to the community. And I believe doing that makes the program better because the Resolve team is actually reachable, responsive and reasonable. That means a lot. Walter Murch, only the greatest editor to ever live:
