I saw this card (https://www.scotiabank.com/ca/en/personal/credit-cards/visa/momentum-infinite-card.html) offered by Scotiabank that offers 10% cash back on purchases within the first 3 mo up to $2k, and 4% regularly on groceries and recurring payments. From first glance, it looks really good, but at the same time, there's a $120 annual fee. Although, the first year has no fee.

I wonder if I could use it for the first year and then close or downgrade it afterward. Would my credit score take a substantial hit?

What's your general opinion on cards with annual fees? What benefits would it need for you to consider one?
