Great! Brings a bit more dynamic into the market. So far, I'm happy with DxO, but I also don't need to manage a library.

I don't know, does Resolve have lens corrections for 100+ lenses built-in? That's the thing that DxO does really well: Lens corrections, matching your camera's color rendering, denoising. Unfortunately, they still struggle with HDR output.

I imagine the tools in Resolve save you much time, due to automation. Probably handy if you shoot a lot. Yet, the biggest difference is that in photography, you're not necessarily limited by throughput. You can and do actually put a lot of effort into single images.
