That is good to hear.

Supposedly the free Chase cards have comparable rental insurance. The main difference is Sapphire is always primary insurance, but Flex and Unlimited become primary when traveling internationally and if you happen to live in a place that requires no car in the US and you don't have insurance, it becomes primary in the US too.

Not sure what the differences are when filing claims though.

I will say this, it seems like more and more countries are starting to require Third-Party Liability (TPL) insurance and the Chase cards don't cover that so you still end up having to pay out of pocket for partial coverage (Chase for CDW, TPL from the rental agency). Some rental places don't make it easy to split these out.
