OK . all the points now I can think of where millenia cc is better than sbi cb
- Millenia rewards education and jewellery purchases. If quarterly milestone of 1L hit you get 1K voucher too
- Occasional spend based offers like spend 6k get 500 agv
- FK BBD sales have instant discount on hdfc core card
even if you pay 1K you get 1K worth reward points and effectively you are just paying 180rs GST thats all.
