You can turn off track comping, you need to turn off the overdub button (that big plus sign in the top left).
What parts of the audio editing is weak to you? In my opinion, it's one of the strongest things it offers. I assume you're trying to edit the audio in the arranger, instead of in the clip view. What makes it so strong, is that you can chop it up in the clip view, and your audio in the arranger remains one contiguous piece of audio.
