@CosmoglotJay I use Procreate a lot and the only brush that I haven't had much luck replicating is the watercolor brushes that Photoshop is capable of doing. I was hoping that the new 5.0 version could do it, but I'm finding that it's falling short a bit.
I'm going to attempt to export the watercolor brush I use and see if importing it into Procreate will retain its capabilities but I'm not holding by breath.
It's a really tough comparison because they do certain things better or worse than the other. For example, inking in Photoshop is terrible once you get used to it in Procreate. It's not even close. I love using both in different ways at this point. But, I could say if you're primary job was producing finished art, you could exclusively Procreate no problem.
