Best cards available right now

I just applied for Tata Neu Infinity card via HDFC. Looks like it gives me good discounts on Tata ventures like Air India, Taj Hotels, etc. I hold a regalia card as well. But it seems like it doesn’t have the complimentary lounge access anymore. What are some good options? On a side note, I’ll be travelling to Europe (yes, for EURO) in June, so I’d like some good cards to maximise benefits. What are your best go to cards category wise? - Travel - Online - Offline - Hotel bookings - UPI - All rounder Etc
