Give them a shot, I actually like mine. I think they're decent cards, although I wouldn't use them to perform.
Like Dana Hocking already posted, it's not like bicycle gave them the choice of "good or bad stock" or something like that, it's more a matter of what you use them for, and what your personal preferences are. Chances are you like the current edition better then the new ones.
I haven't used mine that long though, but it's not a deck that I intend to use that frequently, as I prefer Tally's, Bike's or some other "normal looking" cards. I'm not that into designed decks. Anyways they say they clump up if you use them too much. Time will tell.
Hope that helps.
Cheers
