SBI Elite is a good card despite the hate being poured on it.
If you use it for 5L a year and spend atleast 40% on accelerated categories (grocery, department stores, dining) you can easily net a return of 3.4%. 4.4% if you consider the nice BookMyShow BOGO benefit of Rs.500. And you get the 3.4% as statement cashback which you can use to buy literally anything online or PoS. You are not stuck with vouchers of things you don't want (SCBU). Then there are the 12 yearly airport lounge visits and all 8 of them international.
The bummer is no easy renewal fees waiver. But if you are a high spender they will consider waiving it off from what I heard.
The problem with Prime is that milestone benefits are all vouchers, that too Pizza Hut or apparel stores. And even if you spend heavily on accelerated categories you will find it difficult to go above 1.8% returns (excluding vouchers).
