I also would go try them at the mall. Different hair types work with different types of products. Also some of the products online will not heat up enough, or will damage your hair.
If you have the budget try going to the beauty product shop on SZR near mcdonalds/crown plaze.

Why don't you go to the hair stalls in the malls and try them out yourself
The girls there are really helpful and can advise you rather than asking which one we would use
We all have different hair so probably cannot advise you correctly as your hair will be different
