Why is Valkyria Chronicles good?

they do it through the characteristics of the side characters (such as allergies and people they get along with), through voice acting that actually gives you a feel for what type of person the side character is, by making sure no two look alike, and finally by giving you a bit of the background for each one.

Honestly I think it is mainly the voice acting and visuals that do wonders to give each character a personality of their own.
