I too compose in Finale exclusively at this point. I have taken the time to create some Human Playback expressions and use the dump library provided by the folks at Vienna. I used to think what's the difference between spending hours in a DAW manipulating individual notes and phrases by adding controller data, etc and dong it in Finale. And to some extent I still think this is true.
However I've started entertaining the idea of buying a breath controller (TEControl) and playng all the parts in once I'm satisfied with the composition. I've not heard more expressive realistic performances than what people get with those controllers. The part that always frustrates me about using a notation software AND a DAW is if you decide to change something you have to touch it twice. But I suppose there's no way around it.
The other consideration is why you're writing and what you're writing for. If you're writing with hopes of a live performance then of course you have to produce a nicely engraved score and parts. Otherwise you could consider not using notation software at all.
