I'd dare say that unless you've already learnt Photoshop (and have to unlearn it) then Darktable+GIMP works fine for home photo editing.
If you're used to Photoshop and your skills with it is what puts bread on the table... then I completely understand not switching tools.
As somebody who has been trying to decided which of the RAW photo editors to use, I can tell you that Darktable has a steep learning curve over Lightroom. The UI is incredibly dense and the names of sliders don’t make sense unless you’re an image science expert.
I'll take your word for it, I've never used Lightroom.
Whenever I played around with Darktable it seems finding a tutorial to get the effect I wanted was just a minute of searching away, and there's a ton of beginner tutorials available too. https://www.darktable.org/2024/12/howto-in-5.0/
But then I was the kid that rtfm the game manual on my way home from the store and love dense UIs as an adult. :)
Darktable is a godsend to me for converting film negatives.But I pretty much only use image conversion, RGB curve, then fidget with the exposure and RGB sliders in negadoctor a little more then I'm done. No idea how to do anything else.
Been usin DT for close to a year now. I agree the learning curve is a little steeper than light room but once you get it, everything clicks into place. I can't believe how powerful this program is and it's free. It's unbelievable
The same with Lightroom sadly. The open source alternatives are either too buggy or have UX designed by very "opinionated" people, making them painful and frustrating to use. I currently want to get rid of Lightroom but can't.
You could give Photopea a try, if you're looking for a free (as supported) alternatives, it has all core functions and a interface that looks very familiar. No installation required so you can easily test it, and use it in any browser (not sure how well it works without mouse and keyboard or low end devices though).
If you want more than core functionality I don't think there is a (legally) free option out there.
