I've been having a hell of a time getting cuing to work decently with Traktor Scratch Pro. I didn't bother setting up Traktor Scratch 3.4 so I have no comparison, but I have used CDJs a bit and I can't seem to cue the way I do on CDJs. The tempo detection also seems to be erratic. Sometimes it works fine. Other times not at all.
I have hope that I can get this thing to work though!
