Depends.
Which one makes a bigger dent for your rewards. pick one between 5% on Flipkart or 5% on utilities.
Select might not be worth it for 3k+Gst but for LTF it's a great deal. And this can replace your Ace card for offline spending, almost 80% of regular transactions are retail. which will give you 20 EP / 200 RS. with your privilege card and multi brand voucher that's 4% return.
and the big basket, bookmyshow and Swiggy offers are icing on cake.
RM's might accept the request for LTF cards but they never push us for applying LTF cards. OP might have salary account with axis and 50k+ salary.
