I switched from Sibelius after using it from 2006 to 2018. The learning curve takes some time but isn’t as bad as I expected, I think within a couple of months or so I was about as fast at note entry as I had been with Sibelius (but early on the first-duration-then-pitch approach, and having to switch between write and engrave modes, did mess with my head for a while).
The main appeal of Dorico is for me the quality of the engraving and appearance of the scores; it looks about as good as SCORE while being significantly less work (although at the moment also less customiseable, but honestly not by much, and the native support for things like microtones and extended techniques is superior to SCORE in most respects).
My background is exclusively in classical composition so I’m looking for notation software, rather than e.g. a DAW or something that does playback properly; but from that perspective I think Dorico is probably the best software available & will continue to be so for some time.
