The only main difference is the design, which has an 'old' feel to it but you can tell it's been designed into the cards. i don't know if you'll get a lot of people believing these are 'antique' decks, the 'yellowing' and 'aging' of the cards look printed on.
They handle well, and the finish is what you can expect from Bicycle cards. of course they are a step up from regular cards because these have been designed and printed with 'performing magic' in mind
the 'practicality' and 'motivation' of using these cards versus others is of course up to the performer
