I like the black rider backs a lot. I enjoy doing magic with standard bicycle cards because if you destroy or give away a card, you can easily go get another deck at your nearest target. I have also found that sometimes if I'm using a fancy deck, people assume its marked or gimmicked in some way. I have found that using standard cards (for the most part) eliminates this and people think I can read minds or whatever. I like the black rider backs a lot because they are similar to the normal household deck of cards so nobody expects gimmicks or anything, but different enough that they are appealing to look at.
