I can see 2 important differences:

- Does the ISA you're emulating have an actively developed hardware
  implementation against which you're going to have to compete?
- Do you expect to spend 99% of your time emulating a foreign ISA, or do
  you expect to mostly run binaries using your native ISA and just
  occasionally emulate another?
