I recently did a big comparison of RAW processors as well, although for a slightly different reason: faced with choice, I tend to become overwhelmed, and can't stop thinking "what if". What am I missing, by limiting my knowledge to one tool? What if my pictures could turn out better, with less effort?
And the only antidote I know is to try them all. So I did, and you may read about it over here:

I took a bit of a different approach than most comparisons I have read: I simply can not deeply learn a dozen tools with the required depth to wield them well. So instead, I will edit a few pictures with clear defects with only, say, the highlight recovery tools, and see how the results compare. Which does explicitly not evaluate "features" or workflows, but at least is somewhat objective.
I tried the "just play around" approach as well, but the only thing that did for me was make me even more confused, and blur the differences between tools even further. They are all capable of editing an image after all.
The conclusion of this experiment was successful; I can again sleep at night without worrying about image editing software. And happily use Darktable as I used to, safe in the knowledge that it is perfectly adequate for my uses. And I did learn a few new techniques on the way.
What I found in terms of processing, however, was extremely surprising: most RAW editors show obvious and severe artifacts and aberrations. Never mind detail rendering, denoising, and color rendering. I'm talking about magenta fringes on every burned highlight, huge rings around a sunset, colors bleeding from a subject to the background.
The best in terms of these aberrations, was without a doubt Lightroom, a program I don't enjoy using for as of yet badly understood reasons. And, surprisingly, my venerable Darktable actually fares very well in this regard, no doubt partly due to my familiarity with it.
Perhaps it is my background as a scientist and software developer, but Darktable simply fits my way of thinking very well. It allows me to reason about an image in signal processing terms, which is familiar and comfortable to me.
And thankfully, there are so many approaches available out there, from scientific Darktable, to the very polished and "designed" Capture One, the workflow-optimized Lightroom, to the magic AI automation of Luminar. Everyone ought to be able to find a tool that fits their preferences in that enormous list.
