I think you're creating a false dichotomy. I used to believe that I was the "artist" type, but I was mainly just a procrastinator who didn't have good work habits. I became the "steady progress" type as I took on bigger, harder projects. And honestly, passion is a lot harder to come by when you're working on an intractable bug six years into a long-term project. If you rely on the muses to guide you, you rarely get things done, because that last 1% is rarely ever fun.

Also, you might be surprised by how many artists have a strict routine, and dedicate themselves to a regular pattern of practice. Twyla Tharp wrote an entire book on the subject:
