Neon tetra or cardinal tetra?

not sure which is better. i have a 30 gallon tank and just want one of those kinds but they look the same to me. which is better and why? and also for whichever is better, will they schoal with black neon tetras or no? like if i got 4 neons and 5 black neons, would they all schoal together?
