I work and compose mostly in Logic Pro 9. I'm not saying its the best. Its just what I happened to hone my skills in and its the Daw I'm most comfortable with. Frankly I'm not even that proficient with all the amazing things it can do. I do make it work for me though.
For anyone else that uses Logic. There are a number of Logic forums/websites that may be helpful to you. One of the cool Logic sites I visit is http://logic-cafe.com. Pretty cool and they always have free sound downloads for the exs24 and other logic instruments. Enjoy!
