"The two seem to get along."
"The two don't seem to like each other."
"The two prefer to play with other Pokémon than each other."
The last one (the pokemon prefer to play with other pokemon) means the pokemon won't breed at all.
To get the highest chance (they match perfectly), the pokemon should have the same pokedex number (they're both the same pokemon) and different original trainers.
