Eh, I'm not too sure on the difference between the brands, but I do know that the kinds of cards are not all alike. The higher end cards have a high write speed (I think that's what it's called). It allows data to be written to the card faster. However the higher end cards will be more expensive. I know that Lexar is a decent brand of cards but I don't know about the others.
