It would also be of help to know what size your tank is and what your water parameters (hard, soft, acidic, alkaline?) are. I know both Ram's and Apisto's are very similar in water requirements, but there may be some little thing to throw it one way or another.
IMO, there are a lot more types of Apisto's to choose from, but you can't go wrong with Ram's either, if your heart is set on one or the other of those two choices.
