I am EU citizen travelling to Switzerland soon. Would it make most sense to make my payments with maestro or with my mastercard ?
This depends a lot on the terms and conditions of your mastercard. I generally pay with credit card since a) I get 2.66% cash back and b) there is no foreign transaction fee. If your mastercard charges fees and/or doesn't offer benefits, use the debit card instead.
How about cash withdrawals ?
NEVER EVER use a credit card to get cash unless you have absolutely no other choice. The interest, fees and malicious payoff rules are banking at its worst. Use your maestro debit card for getting cash. This can still incur a fair bit of fees, so using good credit card is the best choice. Try to minimize your cash needs.
