Regarding notation tools, Sibelius is outstanding. I used Finale a long time ago and found Sibelius far superior. I expect that Finale has improved since then, but so has Sibelius. Most importantly, these are Notation tools. Logic has a notation section but it is nothing compared to Sibelius or Finale. Logic does many things very well however, if I want to write music, as opposed to recording music, I will use a notation program. I then save as a midi file if I want to bring it into Logic. Why am I saying all this? It is of primary importance to determine how you want to create music. Someday, perhaps, DAW's and notation programs will be one and the same. As of now, they are not, although there is quite a bit of overlap. Just as a garden rake is not a garden hoe, you must pick the tool that works for the job you have.
