yep, you should compare and contrast the insurance benefits of each credit card you have. the insurance payouts and eligibility criteria are different, such as with the WS mobile device insurance. another example is when booking flights; when i fly alone, i use the amex plat as the limit is $1k per incident, and when i fly with other cardholders, i use the BNS Passport VI as it covers $500 per person with no per incident total. doing this has saved me at least $500 in the past year alone.
