Workflow changed with darktable 3 and to get the most out of it I recommend reading this article: https://pixls.us/articles/darktable-3-rgb-or-lab-which-modules-help/
Many modules - that still work - are now deprecated in favour of RGB workflow new modules. The article above suggests proper alternatives for each of them.

TLDR; lies.
Kindly substantiate your claims.
DT has a clone tool. It's part of the retouch tool.[1]
Which is very powerful and allows way more than just cloning. It is also non-destructive, like anything in DT.
DT has camera profiles, new cameras get added regularly.
You can also create them yourself if you have access to a color checker using a built-in tool.[2]
DT has tons of lens correction profiles. Basically anything you find in lensfun.
If your lens is missing, lensfun has a service where you send images and they send you the calibration data back and add it to to their database.[3]
I shoot (often exotic) manual glass most of the time.
If someone tells me DT is lacking in this regard it's a good indicator for me they have no clue what they are talking about or never used the app seriously.
UI: it could see improvement in terms of parameter exposure (no novice/simple mode) and ranges (some sliders go from 0..1, others from 0..100%) but otherwise?
What in the UI is prehistoric?
The catalog part of DT is also great. i.e. when your catalog is on a slow network or cloud drive DT can automatically cache RAWs locally and send back the XMPs with the edits only.
Caveat: I regularly get paid for photography work (it's not fulltime but give I worked professionally in blockbuster VFX for two decades I think I qualify).
I do all my processing in DT. If I have to do compositing work beyond that I export to Fusion.

There's some nice GIMP tutorials here with good showcasing.
https://pixls.us/articles
I believe written by GIMP contributors.. including Pat David who did a ton of older and a bit less polished ones here:
