I usually use Logic for my production, as I'm more into electronic music. However, when I make more kind of acoustic music, I use cubase as I find working with audio is a lot easy and generally better in cubase than it is in Logic
Still my main DAW. Haven't gotten into actually updating to a newer version. I do a lot of work day in and day out on Cubase 6. Regardless of where I start a piece of music, everything ends up in Cubase.
