Are cashback cards underrated?

Okay, I (28M) have been using credit cards for nearly six years now. I haven't owned any premium cards, considering my spending is erratic and inconsistent, making them less beneficial for me. Instead, I've been collecting lifetime free (LTF) cards. However, about a year ago, I added two paid cards to my portfolio: the HSBC Live+ and the SBI Cashback card. Since both these cards come with fees, I wanted to keep track of my spending and the cashback I received from them. As I was already monitoring this, I decided to include the HDFC Swiggy credit card as well, which was provided as an LTF card.

Additionally, I have the ICICI Amazon card, another cashback card, although I haven't used it much recently as I've switched to the SBI Cashback card for most online purchases. Combining the cashback from all three cards, I'm getting an overall rate of 4.57%, which seems impressive and on par with many premium cards on the market. What do you think of this? I would think even Airtel Cashback is something which could top the list.
