The title says it all. Is it better to stay with the Platinum card which looks to have more benefits for the traveler (Gold status at different hotel chains for instance) or change to the Aeroplan Platinum card which might (emphasized as the new Aeroplan doesn't come into effect until November) give more benefits when flying on Air Canada. Most of my flying is with Air Canada but not all. After the $200 travel credit with the Platinum card the cost is the same. I guess it's an individual choice.
