FHI Heat Platform in Pink or Corioliss Purple Haze hair straighteners?

Which do you think is better, Fhi Heat platform straighteners in pink, or Corioliss Pro Purple Haze straighteners? I think they have similar spec, but I'm getting a pair for christmas and I just want to make sure i'm gonna get the right pair! I've heard a lot about the FHI's and think they're really good, but I prefer the purple colour of the Corioliss. However, I can't seem to find much info on them, and there only seems to be one review about the purple straighteners. I went to Sally Hair & Beauty and they said that Corioliss were good, but i'm just not sure if as good as FHI. Also I can find FHI for cheaper online and only 2 sites seem to sell the purple Corioliss. (I'm from the UK). What are peoples' experiences with these straighteners? Please don't mention other brands, I ONLY want information and reviews about FHI or Corioliss straighteners! Are Corioliss solid ceramic or coated? Because I think they're meant to be solid ceramic but i've read some reviews that say not. Thanks!
