They are all quite different! Ableton is good for realtime stretching of solo instruments and voices, while PT is also capable of handling complex mixes. PT has several algorithm options, including X-Form based on iZotope Radius.

Wavelab 6, 7 are based on Prosoniq DIRAC. My personal (maybe biased) opinion is that it's not as good as the latest Radius, at least not in Wavelab, - it makes all transients "chirpy". I've seen a better implementation of DIRAC in Time Factory 2.

They may be based on different versions of Radius. Elastic Audio in latest versions on PT should have the latest Radius in it.

I'd appreciate if you share a sample.
