I’ve compared the two a while ago, seems to me like slightly different takes around the same core ideas. It’s true that a couple of things in Ansel feel more natural, but it’s not much, and it’s probably not worth the risk (AFAICT the bus factor is one, compat with DT isn’t a goal).

Darktable developers pride themselves for their non-destructive processing pipeline and use it as an excuse for how quirky and inflexible their UX is. I believe they are highly competent on the highly technical bits that ultimately very few people see or understand. Personally I can use it to an extent if I unlearn what other software have taught me over decades of UX conventions.

Don’t ever bring this to the people in charge or you might be told “sorry for that” “but now it’s been fixed, deployed any week now” “you are a liar, this has never been true” and “it doesn’t really matter for the general case” either in the same post or few responses apart. Matrix has been in a permanent state of unstable mess, and the leadership disingenuous attitude made me lose hope that this will ever change. More people should start reading through the fanfare and superlative blog posts, which, admittedly is the thing they do the best and much better than the other projects out there.

And so damn easy to self-host in general. Ejabberd is batteries included down to offering stun/turn for audio/video calls, Erlang is just unrivaled when it comes to hot reloading so updates are effectively zero-downtime (unsurprising considering all the business critical environments it’s deployed).

At first (and especially because I went with Matrix originally) I wouldn’t think of self hosting all my instant messaging, but in retrospect, ejabberd is one of the easiest services I’ve got to maintain. I highly recommend everyone to give it a shot, especially to all the matrix refugees to whom it was a surprise/disappointment.
