Not sure what you meant by "but the implications of one over the other and getting similar results"

If you're saying "one is neither better than the other if they get the same result" then, you've got it - toss a coin.

It'll be difficult to assess the work either would take though. If someone's willing to be persistent with affirmation over a period of time, fine. It could mean more work but....depends on what you have to do to prepare a rite.
