What you need to do is have a third copy observe your two copies run in
parallel, and have the third copy decide whether it's better. If the third
copy can't decide either, then I propose that you simply don't care very
much. To take the music analogy again, if you can't decide between
Beethoven and Mozart after hearing them both, then you're not likely to be
willing to spend much more resources on one over the other.
