If you are or were happy with your GHD, then stick to it. Flat irons are pricey and you might buy a product that you are not too happy with in the end. I don’t see a reason not to try a different brand, but be sure to completely research your options before you. Go on the net to see how many other people love the product, ask around at salons or friends who are also using a different brand from GHD. If you are not happy with the results then stick to what you know best.
