This is a silly question I know, but I'm not too wise on financial knowledge. I'm travelling in Europe and I have both a mastercard credit card from a Canadain bank and a Wise prepaid visa debit card with euros on it. I generally use the latter for daily expenses - food, drink and so on.

But when I book activities on an app like Viator, I use my credit card because the costs are in the 100s of dollars and its online so I assume it's worth doing it that way for the rewards? Viator is based in the UK I believe if that makes any difference.

Should I be paying with the credit card for those benefits or with the Wise card cause this company is in Europe? Thanks
