A frequently asked question is whether I have a set of recommended cards to hold. It's challenging to provide a generalized answer without knowing your spending patterns, categories, and total expenditures. Instead of giving a broad response, I will share the cards I hold and how I use them. From this list, you might find cards that suit your needs and spending habits.
This list does not necessarily represent the best credit cards available, but rather the ones that work well for me. Your experience may vary. I recommend reading this post - How I think about Credit Card Points, to understand how I view and use my cards. This is not a detailed review of each card mentioned, but a brief overview of their key aspects and how I use them.
