re: Opening new personal credit card for rewards purposes. Which one’s right for me?

I have the AMEX Platinum and the Chase Freedom Unlimited. The AMEX doesn't have great cash back (5x points per dollar spent on travel, 1x for everything else) but it has a ridiculous amount of statement credits. $240/year for streaming services, $200 hotel credit, $200 airline credit, $200 Uber credit and complimentary gold/elite status at Mariott, Hilton, AVIS, and Hertz. Also gives you lounge access. It's a steep annual fee of $695 but it's pretty dang easy to break even at a minimum just based on the things above. Main reason for signing up with them was they had 150,000 point sign up bonus.

They also have great transfer partners but you have to really study up on that (like the poster said above) to get real value out of that.

I put everyday purchases on the Chase card and big purchases on the AMEX.
