Looking for best card for milestone rewards/Cashback and Government transactions.

[Nikith]

I'm looking for best card for milestone reward/CB.
currently I'm using Kotak royal card, it will give 30k points on 8L spend (roughly 7500Rs).
Mostly I'll do online transactions (especially Government) around >30L/annum.

Kindly suggest best credit cards for
1. Government transactions
2. Milestone benefit
