"Safety information I found indicated the Prius was a bit better"

Which information was that? I had only seen the Gold IIHS rating and the front/offset/side/rear ratings for the 06 Civic. Haven't seen the complete ratings or any IIHS ratings on Prius. Historically the Prius has done well (with side curtains and active head restraint) but I see no evidence it is "safer" in the 2006 model year.
