I wish to clarify that composers who (can) literally write music, and therefore use notation software, are by no means more talented than those who don't/can't.
However those that can -and I refer to those that can write a fully orchestrated score, not just a melody and accompaniment on a couple of staves- I would say they invariably do (unless a contract is very rushed and the music simple enough, say 'Epic' for example). The reason is that these composers are invariably better schooled (either institutionally or privately), and they can put on paper exactly what they want, in detail that one cannot achieve in a DAW easily. The person that does not notate can be talented but is slave to the available sampled instruments and articulations on their computer, as well as their MIDI and programming skills (which have little to do with the actual orchestral music). To drive the point home, in the 'serious' music world there are many composers who still do not use computers, and instead handwrite everything because computer notation has not yet become sophisticated enough to accommodate modern music's notational requirements without major workarounds. Also you know what? A lot of these people can notate complex orchestral scores without needing 'Playback' to test their intentions.
They in fact can write music for the concert hall, across genres, so they are not limited by a style of music that is achievable by software particularly tailored for this purpose. They use polyphony instead of building 'layers', etc...
These people are not superhuman or hugely talented necessarily. All they did was spend a couple of decades developing these considerable skills.
