With SGX you don't have to trust the cloud provider, but you still have to trust Intel. Of course, you're probably trusting Intel anyway, so this is perhaps just a theoretical concern.

With homomorphic encryption, you have to trust Intel to build CPUs that calculate correctly. Except for FDIV style bugs (which are pretty rare, and it's telling that FDIV, from the mid-90s is the go-to example), they mostly managed to maintain that trust. With SGX you have to trust Intel to build CPUs that isolate securely. Meltdown, Spectre (multiple variants), bugs in Intel TXT and ME, and that's only some of the headline issues from the last 4 years.

  ...and if there are bugs, with SGX they could expose your secrets. With homomorphic encryption they should just turn your results into detectable garbage on your end, I'd expect.
