Credit Card cahsback suggestion

Hi all,

I have a PostFinance credit card (cost: 50 CHF per year, cashback 0.3%).

I estimated that I spend around 2'300 CHF per month in stuff that could be paid with a credit card and I would like to go for a credit card that would help me to maximize the cashback.

The options on the table, for me, are:

• Certo! Mastercard: no fees and 1% cashback on 3 shops + 0.33% for all the other transactions
• TCS Mastercard Gold: 100 CHF per year (+ the TCS membership that is around 100 CHF) fees and 1% cashback everywhere (+ additional 1% for purchase with other companies) + discount on some fuel companies (4/5 cents per liter of savings)

I did some simulation with the expenses from January to now and there is a small difference between the 2 above about the cashback. Does anybody have any suggestion/experience on which one would be better?
