Which is better Sedu, Chi, or Solia?

I have a Chi Turbo right now and HATE it. I had it for like 2-3 years at first it left my hair shiny but now it smells when I turn it on and it makes my hair smell and it causes breakage. I used to have a straightener by Conair (before they came out with the Infiniti line) and it was the best ever but they don't make it anymore.
