The other thing to look for is primary vs secondary coverage.
In the US, Diner's Club is primary and so are some business cards (but only when renting for business).
Chase UA Signature Visa is secondary in US but primary elsewhere.
Something else to look for: if they cover loss-of-use. Amex cards typically didn't for example but that's changing I believe.
