Has anyone used both a CHI and a GHD hair striaghtener, which is better?

i love both of the straighteners, but i think for your type of hair to go with the ghd straightener, it stops frizz and it straightens curls for a long time, it will stay straight until you wet it. but with the chi you have to straighten it periodically in order for the straightness to stay. i would really recommend getting the ghd protectant spray because if you use it a lot it will give you the worst split ends and the ghd will burn your hair if you keep it in one spot for a long time. the chi isn't as strong so it won't burn your hair if you have it on your hair for a long time, but it will give you the terrible split ends.
