Given that MultiPay CI is more expensive, is there any benefit in taking up MultiPay CI as compared to getting an Early CI + Late CI Coverage?

Priority should be given to a larger single claim. Multipay claim will be a supplement to that.

It would depend on the policy term also. So a Term to 65 for both options are quite close, but once you extend the Multi Pay Term to after 75, it gets a lot more expensive than single claim types.

There is definitely benefit in Multi Pay, but I would apportion a small amount to it, and have most of my claims still be a bigger single claim option.
