It's like the Cadillac of hardware wallets. You can find its functionality in other, lower-priced signers, but it's almost a luxury experience.
The Passport Prime is going to be crazy when it's released. It's got a lot of other premium features, including that you can use it as YubiKey, and it has an encrypted file space to store important documents unrelated to transaction signing. And I think it can also be used as a FIDO2 key.
It's going to be expensive AF, probably in $500 range, but I think they can justify the price with all the features, and premium hardware.
