I will be doing some rentals in the USA and Ireland and I see my Chase Sapphire and Explorer both offer primary CDW. The Amex Business Plat offers a secondary coverage (but in my case it would be primary as I don't have a vehicle in the USA).
What are the differences between the 2 in terms of coverage? For example, does one cover towing (if the car got stuck but was not damaged in any way) vs the other? Are more cars covered on one than the other? Has anyone had to deal with Amex or Chase with a claim and can share their experience?
I'm just thinking which car I should use for the rental.


Thanks
