whom is an object pronoun. in other words, it's used in the same context as are other object pronouns, such as "me", "him", "her", and "us".
who is a subject pronoun. in other words, it's used in the same context as are other subject pronouns, such as "i", "he", "she", and "we".
in this context:
the correct form would be "we like HIM/HER best". you would not say "we like HE/SHE best".
this means that you need an object pronoun in this context. therefore, you need "whom".
