Welcome to WebmasterWorld :)
I have never used Adobe Streamline but can vouch for Illustrators live-trace tool - really bloomin' great - I have used it to pretty good effect on a variety of jobs - from art working small comps to multilayered vector based illustrations.
If Adobe streamline was used to trace objects as vectors I think you should be pretty happy with the results of Illi live-trace too.
PS - this is a handy starting point: [webmasterworld.com...] ;)
