Darktable is basically the only software I use so I can’t really compare… it definitely does have a learning curve and it’s quite technical (designed for nerds, by nerds), but (being a nerd myself) I find it rather natural to use.

In a sense darktable is more a collection of modules bound together in a framework than a monolithic/cohesive software. On one hand, this means you have to learn each module separately; on the other, it also means you can ignore most of the modules and only look at the handful you’ll actually use.

Definitely do watch some tutorial to get started with darktable (if only, to understand the general workflow which modules you want to use).
