I'm still waiting to hear a side to side comparison between Cubase's Audio Warp and PT's Elastic Audio. I almost never use Time Stretching, I almost always slice and slip / crossfade for editing, even for DIs or vocals... I never got used to these tools. In fact, I don't even know if they're any good, but for the 2-3 times I DID use them, I didn't see any more blatant differences / artifacts on either of them.
