I'm not sure about that, they don't have the same shell so would perform differently. Doesn't mean one is safer than the other but seems a strange comparison. I'd say the sales rep was pushing SnS hence the CREP comment seeing as Infa is starting to perform as well and in some cases out perform SnS there. I honestly don't know a lot about the Safeguard though so can't really give an opinion on them either way. I do know lots of people love the Neons and Kompressors and have kids RFing up to 3 years in them.
