It's the finish that makes it feel that way. Rosewood boards are not typically painted/cleared with any finish. A bare maple fingerboard feels great, the grain is nice and tight too so it's smoother feeling than rosewood. I've never played a roasted maple neck or fingerboard, I would imagine it's more of an aesthetic than a feel, unless it's is not covered with any finish. But even then they do rub the neck with oil and it's an oil finish. I prefer an oil finish. Sticky finishes are definitely not my cup of tea either.
