Which hair straightener is better?

I am just wondering which hair straightener is better. I have the babyliss pro nano titanium and it works wonderfully on my hair. I have had it for about three years and have had no problems with it. Recently my friend was telling me about the croc flat iron that is ceramic and says it makes her hair look like she just came out of a salon. She says the guy she can get it from sells it for $212 and takes cash only, which seems a little sketchy to me. I was looking it up on the internet and I found it online on amazon for about $70 give or take a few. I am just wondering which one works better, or is better for your hair, or should I just stick with the babyliss pro nano titanium?
