I used to use audition of chopping. But I stopped that not too long after.
As it's already been said, Audition is way overbloated, it's like the Windows ME of audio programs.
If you have PT and Logic (Don't know why you'd need PT when Logic is 15000 times better) then Audition is completely and utterly useless. In all honesty I'd probably recommend Audacity of Audition just from the fact that AA is such a resource hog that you'll have a much faster workflow in Audacity.
I generally like Adobe products, but audio is not they're field AT ALL. They need to stick to visuals cause Photoshop, Illustrator, After Affects and Premier are all prime.
