Which card to choose 6981 or 6922

Hello.
I'm in the final step before buiyng one of the TSB cards and I neeed to choose between 6981 and 6922.
Please give me an advice which one would be considered better and future proof. I don't really care about 6981 being a dual... the thing I care of is card's sensivity and general reliability.
Which one would you choose? Which card provides better technology?
Thank you.
