It depends on what you get, because you don't want to kill the MB because overload the 3pin header. 1) if you use only one or two led strips you can use either. 2) if you use more strips on the led controller, I recommend to use the 4 pin molex from the PSU, because most of 3pin or 4pin header can only support up to 1Amp only.
