HDFC Milennia vs Amazon ICICI cc?

Before reading forward - google a lot for this question and found unanswered posts with no activity.

I took the amazon card as ltf 2 years back and since then it's been good. I use it to make payments, I do less cash withdrawals and I get rewarded for it.

Recently I've been thinking of getting HDFC millenia because apparently its "the best" cashback card around after sbi cashback. Also because this card becomes king when festive season is around.

My question is - is it worth getting it when I'm already getting 3% on non prime amazon transactions? On top of that, the cashback is Fully usabale to pay bills or shop.

Whereas in Milennia you need to pay around 60rs for just redemption.

I've been going through similar posts and found almost no comparison between these two.

My spending is very low <10k in a month.

Should I proceed with Milennia ltf or just say fk it and go with SBI CB?
