It's interesting how the dynamics of credit cards work! Lifetime free cards are great for no initial or renewal fees, but the trade-off is the lack of substantial rewards. On the flip side, premium cards like Tata Neu Infinity and Diners Club Black might have annual fees, but the rewards and benefits can outweigh the costs, especially for heavy spenders. It's all about finding the right balance between fees and rewards based on your spending habits. Thanks for sharing this insightful comparison! 🌟
