I'm currently using Dorico, mostly because I use Cubase, which is by the same company.
I'm hoping that they will one day make the workflow between the two apps really seamless.
I've also used Musescore quite a bit, and it's really great and FREE! If you just need a notation program to write in, Musescore is great and has some good stock sounds too.
I'd recommend Musescore since it's free, but later on if you one day get Cubase, you could then maybe get Dorico.
Just wanna point out that you really don't need get Dorico even if you use Cubase, Musescore works just as great! It's just that i own the Noteperformer soundset which I used to use with the Sibelius notation program before Dorico was released, and then changed to Dorico when they started supporting it.
This is a scrapped track from the last Impressions OST jam that i used Musescore for (the sounds are their free MUSESOUNDS sound package!):
