Premiere doesn't have options for screencast. But you can combine pre-recorded screencast videos with your talking head videos in Premiere. I guess you can do this in Camtasia as well. But for me, Premiere gives much better interface and options to work with audio, imho. And also gives much better precision when working on the timeline/sequences. For the record, I've not used Camtasia for anything other than screencast as I found it a bit limiting for video editing. So my opinion may be a bit inclined towards Premiere 🙂
