I have a biased opinion having to own both. I go with the Argentea which has size, the mother-of -pearl color, as well as the personality which goes for the my large male or the females that are housed in with him. The lone juvenile that I have growing up in the tank with them is about 3 1/2 to 4 inches (only survivor from a prior spawn) and at this point is flaring at its reflection in the glass and has great coloration already (hopefully another male)
