I like the system in general! I can't be bothered to keep track of good vs. amazing, dunno if it would matter to me, but I do pay attention to compatibility when deciding who my sims will try to befriend or become romantic with.
It's kinda fun that they can tell compatibility right away, even before learning the traits etc that the compatibility is based on.
Like the way we get a feeling about someone in real life and are more interested in getting to know them, or more interested in getting away from them quickly :)
