Its worth it, if you are willing to pay the extra price, its all about personal opinion. I payed £40 extra for this when i got it because of the stepping. So in my opinion it is certainly worth it yes.
In most places ask the guys behind the counter and they will kindly search for a stepping you wish for if they have it.
