No, I'm just re-iterating advertising blurb ;-) during the research for 
Jochen's and my data model paper I looked at what the PostGIS topology 
people were doing (their project seems to have died), and in conjunction 
with their efforts found some postings that said, more or less, that 
Oracle had a good implementation of topology-support for their GIS 
stuff, and that the PostGIS people were trying to emulate that (or at 
least using it as a benchmark they wanted to achieve). I thought that if 
the PostGIS folks say Oracle does something well then it would probably 
be true.

I've never used Oracle GIS myself.
