i prefer to use a curling iron. the hot rollers tend to make my hair sort of frizzy, and sometimes the curls turn out a little weird.
with a curling iron you can curl it however you want and if you mess up, its just one curl and you can fix it, not all of your hair.
but everyone is different. you could always try using hot rollers on a day that you arent really going to be doing anything. that way, if you don't like the turnout, its not a big deal.
so you could always just try both out, and see what works for you.
