I'm pretty happy with how AP and AD work now and AP eliminated the need for Pohtoshop for me. I'm an amateur/enthusiast pohtographer anyway. Of course there's always room for improvement and the Affinity applications get that with updates.
I couldn't care less about RAW support. I shoot Olympus and ACR can't handle raw files the way my free Olympus Viewer does regarding colors and sharpness. I can imagine it's like that with most camera brands. So I use Olympus Viewer as the first step in my workflow before I go to Lightroom where I use plugins and use it as a DAM.
But like I said before, a DAM product from Affinity is definitely needed to replace Lightroom. Full Photoshop/Lightroom plugin compatibility would be fantastic as well of course, many of use have quite a bit of money invested in plugins.
