The moves are apples and oranges. I can't compare them because they are so amazingly different. If you ask what's better, the Hermann pass or the Classic pass, then you'll have a very productive discussion. This thread is incredibly entertaining, which is certainly worth something. If you're going to ask a "what's better" question, make sure you ask us to compare things that can be compared, and then give us some context for the question. (I know I'm repeating what's been said a few times before. Sorry.)
I don't use either move very much, but that's because I don't have the confidence to do the DPS, or the chops to do a decent second deal. Personally, I'd use both very often if I were to use them because they are both incredibly useful for magic and gambling demos. In magic you can use the second deal for many things. (I'm avoiding giving examples because they may be considered exposure, although the main one I have in mind is commonly known.) The DPS is a control, and combined with other techniques, it is one of the best controls around for close-up magic. (Closely followed, I believe, by a wisely chosen pass, the over hand shuffle, and a plain old top change.)
