Hey bud - I think most people prefer the look of cardinals since the red runs the length of their body (whereas it stops halfway on neons). Cardinals also get slightly larger I believe. Neons tend to be cheaper and easier to acquire, which is honestly the reason I have neons instead. For your reference, I have seen cardinals at the Rt. 10 Petsmart at the far end of the tank section.
