I say pick the one you like better... I know that is a ambiguous answer, but they both do awesome things in combo.

They can both be VERY nice not their own, and both have a a great Super.

What else do you have? And are you looking male or female. Super high quality females of both can take a little looking to find. Here are pics of my Enchi and Flame (Amir's line of Fire), and both get better and better with each shed.
