It really depends on your travel patterns and what lounges you'll get the most use out of.

Those who have Amex Centurion lounges in their airports will find more value in the Amex Plat.

Chase Sapphire Reserve is good for those who want primary rental car insurance (vs secondary offered on many other cards) and access to Priority Pass restaurants.

Citi AA Exec is great for those who fly AA and want access to the lounges. The ability to add authorized users who can access the lounges is a good perk.

Also, the card being redundant is a moot point if you're signing up for the bonus and closing the card at future date.
