Although it requires more trust, this also has more functionality than an FHE, in that it allows you to deliberately allow selected information out of the enclave. For example, you can check a signature. With an FHE, the boolean indicating that the signature was valid, can only be revealed to someone with the key of the FHE scheme. FHE is not a fully generic way of using third-party hardware in a trustworthy way.
